ITD releases traffic control plan used for Interstate 84 construction

The Idaho Transportation Department has received interest regarding the traffic control plan for the Five Mile to Orchard project on Interstate 84. You can see the entire traffic control plan for project by clicking here.

ITD Construction projects that have shoulder or lane restrictions are required to include a traffic control plan that meet the standards included in the federal and state approved Manual on Uniform Traffic Control Devices (MUTCD). These contractor traffic control plans are used to set up signs, barrels, and other traffic control devices for a project.

Below is a brief description of the traffic control plan:

First, the plans for advance warning signs before the lane reduction. This information can be found on page 14 of the traffic control plan.

The first sign a motorist would encounter is a portable changeable message sign on the right shoulder. This sign read “NIGHT WORK THRU JUNE: CHECK 511”. This sign was placed on the east side of the Eagle Road Overpass.

A minimum of 1,500 feet after the portable changeable message sign, the plan calls for a 4’x4’ orange diamond signs on both shoulders that read “ROAD WORK AHEAD.”

A minimum of 1,000 feet after the “ROAD WORK AHEAD SIGN” the plan calls for a 6’x3’ white rectangular signs on both shoulders that read “INCREASED FINES FOR WORK ZONE SPEED VIOLATIONS.” Following these signs, a minimum of 1000’ away 4’x4’ orange diamond signs on each shoulder are placed with a “SPEED LIMIT 55” box and arrow pointing up indicating a speed limit reduction ahead.

A minimum of 1,000’ feet beyond these orange diamond sign, the plan calls for 4’x5’ white and black rectangular signs on both shoulders reading “SPEED LIMIT 55.” At this point, drivers have seen four signs on each shoulder over a minimum of 4,500 feet. All of this signage is placed before the lane restriction begins.

The next section ITD highlights is the beginning of the construction zone. This information can be found on page 12 of the traffic control plan.

A minimum of 1,000 feet after the “SPEED LIMIT 55” signs discussed above, the plan calls for 4’x4’ orange diamond signs on both shoulders indicating the number of lanes closed ahead. This project closed the three left lanes and the signs at this location on the field read “3 LANES CLOSED AHEAD.”

A minimum of 1,500 feet after these signs, the plan calls for 4’x4’ orange diamond signs on both shoulders indicating the left lane is closing ahead (sign 8 in the figure above). A minimum of 1,000’ after this sign, the taper to close off the lane begins.

The plan allows for two options on how to execute a taper. One option is to have a continuous taper closing all three lanes over 1,980 feet. The second is to have three separate tapers, with a tangent (straight) section between each taper.

The plan for this option is detailed as follows. At the beginning of each taper, an illuminated merge right arrow sign is placed. Orange drums with retroreflective lines are used for each taper and tangent section, spaced no more than 55 feet apart.

Each taper must extend a minimum of 660 feet. At the end of each taper, a minimum straight segment (identified as tangent on the plan sheets) of 1,320 feet (1/4 mile) extends until the beginning of the next taper.

Overall, from the first notice of construction at the portable changeable message sign to the final single lane of travel, a vehicle traveling the maximum legal speed would have more than two minutes and twenty seconds to make the appropriate maneuvers and be in the proper lane.

Cloverdale Road Overpass to remain closed for safety of the traveling public

Cloverdale Rd Overpass is closed for repairs following a fiery crash

The Cloverdale Overpass Bridge will remain closed indefinitely following a fiery crash on Interstate 84 late Saturday evening.

The fire significantly damaged a section of the overpass. ITD inspectors have evaluated the damage and determined the bridge is not safe to travel on. The bridge will remain closed until full repairs can be made. ITD has assessed it is safe for traffic travelling underneath the bridge on I-84.

ITD will develop an emergency contract to make repairs as quickly as possible. At this time, the department plans to remove and replace the damaged section. This is expected to take several months to complete. Details on the schedule, cost, and traffic impact of repairs will be shared as they are developed.

Test pile driving rescheduled for July 9-12 on I-84 at Northside Blvd.

Crews drive pylons into the ground for testing

Shoulder restrictions will be in place on Interstate 84 in Nampa at the Northside Boulevard interchange July 9-12. Crews will be driving test piles in the center median as part of early prep work for ITD’s Northside Interchange Replacement Project.

Pile driving will be done during the day; this work is noisy. No lane closures are anticipated, but drivers are urged to slow down and pay attention in the work zone. Crews will set up traffic control and a work zone the night of July 9 and are anticipated to be complete by the end of the week.  Learn more at itd.idaho.gov/84corridor.

This work was originally scheduled to take place June 18-20. It was delayed due to wet ground conditions.

Emerald Street Connector Overpass opens Saturday

Crews wrap up the repavement of the Emerald St. overpass along I-184

BOISE – Bridge preservation work on the Emerald Street overpass of I-184 (the Connector) between Cole Road and Curtis Road, is complete. The bridge reopens to all traffic beginning Saturday morning (May 19).

Preservation work on additional Treasure Valley bridges will continue this summer at the following locations:

  • I-84, Meridian Road Interchange
  • I-84, Broadway Avenue Interchange
  • I-84, Cole-Overland Interchange
  • I-84, Gowen Road Interchange
  • Broadway Avenue, Boise River Bridge

Unlike at Emerald, remaining work will not require full closures and most work will be completed at night. Motorists can expect lane reductions and reduced speeds.

“Bridge preservation work is intended to strengthen the bridge surfaces and extend the life of the pavement, reducing the need for additional maintenance at a later date,” said Crystal Grasmick, ITD Project Manager. “We appreciate the traveling public’s patience as we work through these important improvements.”

Cannon Builders, Inc. is the contractor on this $2.7 million project. For up-to-date traffic impact information, visit 511.idaho.gov.

Nighttime lane restrictions begin soon for Broadway, Front and Myrtle (US-20) repaving

Myrtle Street

Nighttime lane restrictions will begin in tonight, Wednesday May 16 on Front Street, Myrtle Street and Broadway Avenue in Boise as the Idaho Transportation Department prepares to repave all three roadways.

The project will include milling off the worn asphalt and replacing it with new pavement. Construction is anticipated to begin on Myrtle Street, then move to Front Street, and on to Broadway Avenue in late June or July.

The repaving work is expected to be completed in late summer.

Work includes:
• Myrtle Street between I-184 (Connector) and Broadway Avenue
• Front Street between I-184 (Connector) and Broadway Avenue
• Broadway Avenue between Rossi Street and the New York Canal north of I-84

The majority of construction will occur from 8 p.m. to 6 a.m. All lanes will be open during the day. Occasional work will be scheduled on Friday and Saturday 10 p.m. to 7 a.m.

During nighttime paving operations, two lanes will be open on Front and Myrtle Streets. One lane will be open in each direction on Broadway Avenue.

“To get construction updates, sign up for emails or text messages from the ITD Office of Communication,” said ITD Southwest Idaho Resident Engineer Jayme Coonce. “Dates and plans can change quickly due to unpredictable weather and other factors. ITD will send regular updates to keep motorists, residents and businesses informed.”

To request email updates, text US2026 to 22828. Updates also will be posted to itd.idaho.gov/D3.

ITD estimates 30,000 vehicles travel on Myrtle, Front and Broadway each day. The U.S. 20 resurfacing project is expected to extend the pavement lifespan approximately 10-12 years.

Sunroc Corporation, of Boise, is the contractor for $3.14 million project.

Wet Paint: Striping crews hitting the Treasure Valley

Wet Paint Sign

The last pockets of snow are melting off the Boise Foothills – the annual sign that Spring is in full swing in the Treasure Valley. As you begin to de-clutter your garage and spruce up your yard, the Idaho Transportation Department’s Southwest Idaho office is out in force laying fresh paint on faded road stripes.

During these operations, ITD is asking motorists to use extra caution around the striping machines and the wet paint they are applying.

How the Process Works

Striping crews consist of four vehicles.

  • A lead vehicle to warn approaching vehicles of the wet paint ahead
  • A paint truck that applies the paint and reflective beads
  • A crash truck immediately behind the paint truck for protection and to warn motorists of the fresh paint on the road.
  • A trailing truck with a message board to warn motorists of the wet paint and the painting crew working ahead

When weather allows, striping crews will spend the Spring and Summer repainting all of the lane lines on the state highway system in southwest Idaho. The paint truck sprays two different materials almost simultaneously; the paint first and then retro-reflective beads. The combined materials help the lines remain visible under different conditions: daylight, nighttime, or rain.

Once applied, the paint cures quickly. In ideal conditions, it can be as soon as 30 seconds.

What to do if you drive on wet paint

Wet paint is considered a roadway hazard – similar to animals, debris, or potholes. It’s the responsibility of all drivers to look out for these hazards and try to avoid them.

If you do find yourself driving through wet paint and some of it splashes on your car, you can take immediate action to remove it. ITD suggests two options:

  • Test a small, hidden part of your car first to ensure no side-effects to the paint or finish. Spray the painted areas with Pam cooking oil. Let it sit for a few minutes. Spray off with pressure washer.
  • Use a chemical solvent, such as Goof Off (latex). Test a small, hidden part of your car first to ensure no side-effects to the paint or finish. Spray and wipe off small sections at a time. After you wipe off each section wash that section immediately.

 

Eagle Road to open for Thursday morning commute

Eagle Road Pipe Burst

UPDATE at 5 p.m., Wednesday Feb 7

The Idaho Transportation Department plans to completely open a section of Eagle Road (Idaho Highway 55) near the Village at Meridian in time for Thursday’s morning commute.

Emergency repairs to a broken water main forced the busy road to be closed late Monday night. Meridian Public Works, the Meridian Police Department, Ada County Highway District, and ITD partnered together to fix the pipe, patch the road, and safely divert traffic.

Final paving and striping is expected to wrap up around 10:00 p.m. tonight. When the work is done, the road will immediately open to traffic.

ITD was able to open limited access on the affected area Tuesday night into Wednesday to alleviate congestion during the a.m. commute. The section was closed again at 9 a.m. Wednesday to make final repairs during the day.

This section of Eagle Road sees 49,000 trips on average. Combined with the nearby traffic on Fairview Ave., this intersection is the busiest in Idaho with an average 76,000 daily trips.

UPDATE at 2 p.m., Wednesday, Feb. 7

Crews have closed Eagle Road to make final repairs.

Laying Pavement on Eagle
Crews lay pavement to patch Eagle Road

They are currently laying pavement to patch nearly 70 feet of road length on five lanes and two approaches into nearby businesses.

Work is expected to be completed tonight, in time for the road to open for Thursday morning’s commute.

The asphalt is spread in several layers to promote uniform curing. When paving is done, the patch will have lines painted on it. The road will open to the public when the asphalt and paint has cured and is cool to the touch.

 

UPDATE at 7 a.m., Wednesday, Feb. 7

The section of Eagle Road south of Fairview Avenue, closed Monday after a water pipe break, is reopened temporarily until 9 a.m. this morning. The temporary access will be closed this morning at 9 to allow crews to repave the roadway.

The Idaho Transportation Department has reopened the route to limited access. This involved laying gravel down and building ramps on the edges of the pavement that have been removed.

This requires a speed limit reduction to 25 mph. The public is still advised to avoid the area.

Depending on weather and the cure rate of the fresh asphalt, ITD estimates Eagle Road will be fully open by Wednesday evening.

 

UPDATE at 5 p.m., Tuesday Feb. 6

BOISE – A section of Eagle Road south of Fairview Avenue remains closed as crews make repairs following a burst water pipe.

Exploratory digging
Crews remove asphalt to check for erosion under road bed.

A half-mile section of Eagle Road between Pine and Fairview avenues was closed late Monday night after a broken water main flooded the roadway. The Idaho Transportation Department is working to open limited access on the stretch this evening. This effort involves laying gravel down and building ramps on the edges of the pavement that have been removed.

A limited access will require a speed limit reduction to 25 mph. Should access be opened, the public is still advised to avoid the area. Any access opened Tuesday will be closed by Wednesday morning at 9:00 a.m. to allow crews to repave the roadway. Depending on weather and the cure rate of the fresh asphalt, ITD estimates Eagle Road will be fully open Wednesday evening.

Work today has involved emergency repairs by Meridian Public Works to the water line and excavation by ITD of the road around the flooded area to fix erosion of the road bed.

ITD will post after-hours updates on 511 and its Twitter account, @IdahoITD

Original Story

Burst water line
A crack in the a water pipe closed Eagle Rd. Tuesday.

Eagle Road will remain closed during repairs. Currently, it is estimated the road will re-open Wednesday afternoon. Access to area business remains open. Detours are in place at Fairview Avenue, Pine Avenue, and Franklin Road.

Crews have dug a trench ten feet wide, 40 feet long, and eight feet deep to access the broken pipe. Once the pipe is repaired, ITD crews will repair the road. That includes backfilling the trench, removing broken asphalt around it, and repaving the section.

Meridian Public Works and Meridian Police Department are on scene assisting.

Interstate 84 lane closures between Karcher and Franklin will begin Dec. 4

Interstate 84 looking west from Franklin Blvd. Interchange

BOISE – The Idaho Transportation Department (ITD) has scheduled overnight lane restrictions on Interstate 84 in Nampa next week (Dec. 4-8) to complete geotechnical tests for upcoming improvements to the Interstate. This geotechnical work is one of the first steps of designing substantial improvements to I-84 between the Karcher Interchange and Franklin Boulevard Interchange.

Weather permitting, one lane of east- and westbound I-84 will be closed between 10 p.m. and 5 a.m. from Dec. 4 to Dec. 8.

ITD is planning to widen the interstate, redesign the Northside Interchange and replace the Karcher Overpass and bridges over the railroad and Mason Creek. Improvements are expected to improve safety, capacity and traffic flow in Canyon County for many years. Construction could begin as early as the fall of 2018.

For more information about the I-84, Franklin to Karcher project, visit the project webpage.

South Midway Road Closure Oct. 31-Nov. 5 in Canyon County

 
Weather permitting, South Midway Road will be closed from Tuesday,Oct. 31 at 7 a.m. to Sunday, Nov. 5.

  • Motorists heading south on Midway Road will be detoured to Orchard Avenue via Middleton Road or Lake Avenue.
  • Residents will be able to access their homes using the designated detour route.
  • These closures may vary depending upon weather conditions.

ITD recommends motorists plan ahead, slow down, and find an alternate route.

ID-3: St. Maries Bridge Replacements Schedule Adjusted

In the original St. Maries Bridge Replacements project schedule, the railroad bridge was to be constructed prior to the river bridge. However, with unforeseen delays during the first several weeks, there is no longer time to construct the railroad bridge without impacting the construction of river bridge, and the river bridge construction is the critical path to overall project completion. The project team is currently reworking the construction schedule with the Idaho Department of Transportation. This will NOT change the overall completion date of the project.

The schedule below reflects the new proposed timeline. The only difference between this and the original schedule is the timing of the railroad bridge work:

  • Early winter 2017 through late winter 2018: Crews will construct the river bridge foundation.
    • Riverside Ave between 4th and 1st Streets will be closed intermittently.
    • Additional intermittent lane closures will take place as needed to mobilize equipment.
  • Late winter through summer 2018: Crews will construct the west half of the new river bridge and will complete improvements on Railroad Ave.
    • The road will be reduced to one lane with a temporary signal to direct traffic.
    • Delays during peak hours can be expected.
    • A pedestrian pathway will be maintained.
  • Summer through fall 2018: Crews will remove and replace the railroad bridge.
    • The detour through town will be in place.
  • Summer through winter 2018: Crews will construct the east half of the river bridge.
    • Two-way traffic will be shifted onto the new west side of the bridge.
    • A pedestrian pathway will be maintained.

Please note that this schedule is still subject to change as the design is further developed and as critical subcontractors are secured.

Crews will complete the detour paving today in preparation for the railroad bridge closure in summer 2018. However, for approximately one week in the near future, the railroad bridge will be closed, and the detour route will be put into effect. This will take place as crews repair a utility pipe that broke last week.

Once the pipe is repaired, roadway impacts will be minimal until the river bridge is reduced to one lane in late winter 2018.
