American Falls Interchange 40 westbound on-ramp closed until mid-July

AMERICAN FALLS – The Idaho Transportation Department has restarted work on I-86 bridges near American Falls. This work necessitates the American Falls Interchange 40 westbound on-ramp to be closed until mid-July. Westbound traffic from American Falls and State Highway 39 is being detoured to Exit 36.

ITD asks all motorists to remember to slow down and obey flaggers and construction signs in construction areas. To be kept up to date on construction, road closures, and road conditions check 511.idaho.gov or download the 511 app.

Nighttime Work Begins at System Interchange

Construction

POCATELLO – As temperatures warm motorists will see nighttime work starting up again at the System Interchange project in Pocatello. In addition, there will be short-term detours while girders are placed for the new northbound bridge. As of this morning the east to northbound ramp is closed. Traffic is being diverted south to detour through the Pocatello Creek interchange.

Heavy equipment will be moving earth during the night as contractors rebuild the interchange. The excavated earth will be moved on the large conveyor system the Idaho Transportation Department has been using to limit the need for heavy trucks entering and exiting the Interstate within the work zone.

The massive project requires nearly round-the-clock work during summer months to achieve the goals set by ITD for project completion. During the nighttime work nearby businesses and residents may notice more noise from the heavy equipment moving about the worksite.

Detours necessitated by the placement of girders will be updated on 511.idaho.gov or in the 511 app. While this work continues, weather is major factor for the timing of closures. Motorists are encouraged to keep up-to-date via 511.

Motorists should exercise additional care at night to keep everyone safe. ITD asks motorists to keep their eyes on the road, slow down, obey signs, and be patient with other drivers.

The System Interchange project is part of Governor Little’s “Leading Idaho” initiative that pays for shovel-ready projects to move forward without delay.

 

ITD railroad bridge replacement to begin in Chubbuck

Construction

POCATELLO – On Monday April 17 the Idaho Transportation Department will begin night work to remove the westbound railroad bridge on I-86, just east of Chubbuck Exit 61. The bridge will be replaced with a wider bridge that will have three lanes. To avoid delaying railroad traffic during the day portions of the demolition will be done at night when fewer trains pass under the bridge. ITD expects the replacement of the railroad bridge to continue into early May.

The bridge replacement will necessitate changes in traffic patterns and increased noise. It is important that drivers slow down in the work zone and provide room for vehicles merging or preparing to take Exit 61 into Chubbuck.

There is no need to demolish the eastbound bridge which has already been widened to three lanes

Weather delays planned lane closures at System Interchange

Construction

POCATELLO – The recent snowstorm has delayed delivery of girders for the new I-15 bridge at the System Interchange in Pocatello. ITD planned to install the girders this weekend, but they could not be safely delivered to Pocatello in time. This means the planned lane closures for this weekend will also be delayed until all of the girders can be safely delivered to Pocatello. When that occurs, ITD will update the public.

To protect Idaho’s workers and other motorists, ITD asks those travelling on Idaho’s highways to follow work zone speed limits, be patient, and plan for extra time to travel to their destinations.

ITD System Interchange Construction Accelerates

Construction

POCATELLO – With the arrival of spring the Idaho Transportation Department is ramping-up construction at the System Interchange in Pocatello. As part of Governor Little’s “Leading Idaho” initiative, the System Interchange is being redesigned to replace aging bridges built in the 1960s and improve traffic safety.

While work at the interchange continued throughout the winter, in the coming week ITD’s contractor will be placing girders for the new I-15 northbound bridge. This will necessitate rolling slowdowns, delays, and short detours around the I-86 to I-15 ramp leading from Chubbuck toward Blackfoot.

Additionally, as work progresses into the first week of April the Chubbuck Road bridge will be demolished. This will be done in stages with traffic detoured through Chubbuck at night. The first closure will be for northbound traffic and the second for southbound I-15 traffic.

Other projects will also see ramped-up operations including the Fort Hall Interchange and bridge work on I-86. With unprecedented funding made available for construction, Idaho motorists will continue to see increased activity on Idaho’s highways.

To protect Idaho’s workers and other motorists, ITD asks those travelling on Idaho’s highways to follow work zone speed limits, be patient, and plan for extra time to travel to their destinations.

Drivers need to be careful in upcoming storm

Weather map showing weather warnings throughout East IdahoRIGBY – With a severe winter storm predicted by the National Weather Service (https://www.weather.gov/pih/), the Idaho Transportation Department in East Idaho reminds drivers to take precautions in case roads close or motorists become stranded. Extreme cold temperatures, snow, and wind can make for a dangerous combination.

“We do everything we can to keep roads open,” said Bryan Young, D6 Operations Engineer. “However, we also have to consider the safety of the traveling public and our crews.”

ITD asks the public to think ahead and determine whether a trip can be delayed or avoided during winter storms. Check 511.idaho.gov or the 511 app to learn if roads are closed and to view conditions. If you are driving, be careful to leave extra distance between vehicles, never pass a snowplow on the right, and pay close attention to changing conditions.

Other safety tips include:Image of 511 web site showing cameras and road conditions

  • Keep survival supplies in your vehicle: blankets, flashlight, water, and food.
  • Fill your vehicle’s gas tank before leaving.
  • Be sure your car is well-maintained with fluids at proper levels, tires properly inflated, wipers, brakes, and battery are all in good condition.
  • Dress appropriately for cold weather: heavy coat, boots, gloves, and have extra socks.
  • Prepare to self-rescue if your vehicle is stuck by having: a shovel, kitty litter, tire chains.
  • Inform others of when you are leaving, what route you are taking, and what time you expect to arrive.
  • Ensure your cell phone is charged before leaving.
  • If your vehicle becomes stuck, check to be sure the tail pipe is clear so exhaust fumes do not build up in the cabin.
  • Crack a window to avoid carbon monoxide build-up and only run your vehicle for 10 minutes per hour to keep the cabin warm.

Pile driving to begin Thursday at Pocatello

Road Work Ahead sign

POCATELLO – Beginning Thursday morning work crews at the System Interchange will begin pile driving piers for new bridges. As part of Governor Little’s Leading Idaho initiative, the project was fast-tracked partly due to the aging 1960s bridges due for replacement. The new piers will create a stable foundation to protect the structure of the new bridges.

Pile driving uses a hydraulic hammer that forces piers downward through the soil. Unavoidably, the operation creates noise as the hammer falls on the pier. Work for this portion of the project will be conducted during the daytime. However, in the next week or two additional pile driving will be required at Chubbuck Road that will include some nighttime work.

Motorists should carefully follow signs and posted speed limits while travelling through the construction area. With crews working day and night and with the onset of winter it is especially important that drivers be alert and proceed safely through the work area. Drivers are encouraged to check https://511.idaho.gov or the 511 app to keep track of road conditions and construction.

System Interchange Construction in Full Swing

Leading Idaho - TECM Program

POCATELLO – The Idaho Transportation Department’s rebuild of the System Interchange for I-86 and I-15 at Pocatello is in full swing with crews working multiple areas throughout the worksite. As part of Governor Little’s Leading Idaho initiative, the project is quickly changing how the heart of the Interstate in Pocatello appears.

The lowering of the ramp for westbound traffic from northbound I-15 to I-86 is now complete and work on building the new bridges is beginning. Temporary barriers are in place at multiple locations and motorists will also notice changes in lane striping as traffic is shifted away from work areas.

Cranes are being placed to begin drilling shafts for bridge piers.

One safety innovation being implemented is the use of a conveyor belt system to move earth fill from one area of the project to another. The conveyor allows crews to move material without using trucks entering and exiting the Interstate. That makes for a safer work zone for drivers and work crews. It is important that public keep clear of the conveyor system for their own safety.

In the coming weeks cranes will appear on the project and begin drilling shafts for new bridge piers. Excavators and other earthmoving equipment are also working in multiple areas to reprofile the land. Throughout the work zone water trucks are being utilized to keep dust down. Inspectors and engineers are also on-site daily ensuring safety and compliance with designs.

Near the end of the month or early next month pile driving will begin in the northern portion of the work area. There will be some associated noise during this portion of the operation.

Speed limits in the work area are now set at 55mph and should always be carefully observed, day and night. Crews are working long hours including some night work. Drivers should also know that lane configurations are changing and should be prepared to adjust to the difference by watching for signs and following pavement markings.

It is especially important with such a large project that motorists plan for extra time and to be patient with other drivers by allowing them to merge and change lanes as needed. Sharing the road and watching for workers and construction vehicles entering the Interstate is essential to keeping everyone safe.

The historic rebuild of the I-86/I-15 System Interchange was the outgrowth of a need to replace aging bridges and improve safety. The bridges, built in the 1960s, are currently safe but needed to be replaced due to their age. Failure to do so would result in a need to place restrictive load limits which would hinder commerce.

Water trucks are working tirelessly to keep dust from construction to a minimum.

ITD also noted an increase in aggressive lane changes and congestion within the interchange, particularly just north of the Pocatello Creek exit. The rapid motion of entering I-15 at Pocatello Creek and crossing to the passing lane to exit toward Chubbuck did not exist when the interchange was built. However, with population growth and associated development that traffic is now significant. Such “exit left” and “enter left” movements do not meet driver expectations, cause confusion, and results in frustration for drivers.

Another much-needed improvement was a redesign of the Chubbuck Road crossing. The old 1962 bridge is narrow and has limited capacity for pedestrians and bicyclists. With the growth of Pocatello and the addition of the Portneuf Wellness Complex a significant change was needed. ITD’s new design changes Chubbuck Road from being an overpass over I-15 to an underpass beneath the freeway with dedicated bike lanes and wider sidewalks. Removal of the bridge also creates more space for the larger project to handle increased traffic.

Once completed, the new System Interchange will be safer and ready to carry the increased traffic volumes for the fastest growing state in America.

I-86 to I-15 detour scheduled for tonight

POCATELLO – Beginning this evening at approximately 8:00 p.m. paint crews will be restriping the ramp from I-86 to I-15 southbound. Work will continue through the night and will end at approximately 6:00 am tomorrow. During the restriping work the ramp will be closed and southbound traffic will be detoured through the Northgate Interchange. While it is hoped the work will be completed in one night, there is a possibility the detour will also be used Thursday night to finish striping.

Motorists should carefully follow road signs, obey work zone speed limits, and share the road with other vehicles navigating detours.

I-86/I-15 October Detour

 

I-15/I-86 Detour at Pocatello Ends

I-86/I-15 Construction

Leading Idaho LogoPOCATELLO – The northwest ramp from I-15 to I-86 reopened this morning at the System Interchange in Pocatello. Traffic heading from I-15 toward Chubbuck and American Falls is no longer detoured through the Northgate Interchange. The detour was needed to lower the ramp so new bridges can be built for I-15 through the System Interchange.

Motorists should carefully follow signs and posted speed limits while travelling through the construction area. With crews working day and night it is especially important that drivers be alert and proceed safely through the work area. Drivers are encouraged to check https://511.idaho.gov or the 511 app to keep track of road conditions and construction.
