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.

The Idaho Transportation Department is advising motorists to prepare for construction-related delays at the Lake Avenue and Midway Road intersections on Idaho 55 over the next several weeks. Crews will install mobile signals at both intersections the week of Oct. 23 and prepare to close areas for widening.
ITD is repaving Idaho 55 between Pride Lane in Caldwell and Middleton Road in Nampa and improving the intersections at Farmway Road, Lake Avenue and Midway Road. Weather permitting, the project is expected to be completed in late 2017.
While the mobile signals are in place, left-turning traffic at both intersections will use the through lane. The temporary configuration will give crews more room to widen the intersections.
To give crews room to excavate and pave new turn lanes, ITD will schedule multiple road closures at the two intersections this fall. Each intersection includes two work areas – one north and one south of Idaho 55. Closures will rotate, leaving only one area closed at any time. The four work areas include:
• North Midway Road from Homedale Road to Karcher Road.
• South Midway Road from Orchard Avenue to Karcher Road.
• North Lake Avenue from Homedale Road to Karcher Road.
• South Lake Avenue from Karcher Road to Orchard Avenue.
Each closure will remain in place 24/7 for approximately three days. Residents will have access to their homes during the closures. All other local traffic will be detoured. Click here for a map of the detour routes.
“We are urging motorists to plan ahead, slow down and find an alternate route if possible over the next few weeks,” said ITD Construction Coordinator Merrill Sharp. To sign up for email construction updates, text IDAHO55 to 22828, email firstname.lastname@example.org or call (208) 334-8938. More information is available at itd.idaho.gov/d3.
Crews may start paving the detour route as early as Tuesday, Oct. 24, during daylight hours. This work will take place on Riverside Avenue, Railroad Avenue, 10th Street and 1st Street, and is in preparation for the closure of the railroad bridge.
10th Street between Idaho and Main Avenues will be closed to through traffic on Tuesday, Oct. 24, and the other roadways will be reduced to one lane intermittently as paving takes place for up to four days.
Business access will be maintained, and access through each area will be controlled by flaggers. Please expect minor dust, noise, vibrations and parking restrictions as this work is completed. Visit the project page or call 208-292-8515 for more project information.
Studded tires are legal in Idaho from Oct. 1 to April 30
Snowstorms may not be part of the immediate weather forecast in the lower elevations and valleys of Idaho, but they’ve already made an appearance in the higher elevations and mountain passes. Accordingly, Oct. 1 marks the date for legal use of studded tires in Idaho. Idaho’s studded snow tire season continues through April 30.
While it may be legal to use the tires, officials advise against it unless conditions warrant. Studded tires are snow tires with small metal cleats embedded in the tread, and may cause undue wear on bare roadways.
Studded tire laws vary in neighboring states:
Montana: Oct. 1 – May 31
Nevada: Oct. 1 – April 30
Utah: Oct. 15 – April 15
Oregon: Nov. 1 – March 31
Washington: Nov. 1 – March 31
Wyoming: Legal all year

The Idaho Transportation Department will enhance safety at the intersection of Idaho Highway 72 and US-30 during late September and October.
Crews will reconfigure the intersection to a more common, “t-type” intersection. This will eliminate the free-running movement on ID-72.
During construction, US-30 will be reduced to one lane with temporary traffic signals in place to control traffic. Delays of up to 15 minutes are possible. During the same timeframe, ID-72 will be closed to thru traffic.
ID-72 traffic will be detoured one mile south to SE 2nd Avenue. Truck traffic will be detoured to US-30, Interstate 84, and Sand Hollow Road. Detours will be clearly posted and also available at 511.idaho.gov.
Crews will work daytime hours Monday through Saturday. The project will be complete in late October.
Langley Gulch Culvert Replacement
During the same timeframe, ITD will replace an aging culvert near Langley Gulch on ID-72 near the intersection work and within the existing work zone.

Idaho is home to a lot of rural roadways that present some unique safety challenges. Here are a few recent initiatives from ITD to improve public safety on those routes:
SPOTLIGHTING DANGEROUS CURVES
If you ever played a driving video game, then you’ve seen the big flashing arrows that warn you when a curve is coming up and which way to turn. You’re not very likely to run into the wall, but follow directional arrows around the curve and go for the finish line.
Big electronic flashing arrows might be effective in a fast-paced game, but would not be very efficient on some of Idaho’s rural highways.
RURAL INTERSECTION CONFLICT WARNING SYSTEM
Rural highway intersections can be hazardous if drivers are not aware of upcoming stops and free-flowing traffic crossing their paths. Here’s a lower-cost system to help save lives.
The project previously won ATA regional honors in late June. Idaho’s Thornton project was selected by the judges to move on to The People’s Choice award (and/or Grand Prize) and a shot at $10,000 in prize money. The prize money will be donated to a charity or scholarship program chosen by the winning state department of transportation. The winner will be announced Sept. 27 in Phoenix.
The awards are a joint effort of AASHTO (the American Association of State Highway and Transportation Officials), AAA and the U.S. Chamber of Commerce.
“This shows that the Idaho Transportation Department is being recognized as one of the best transportation departments in the country, and ultimately this excellence benefits all of Idaho’s drivers,” said ITD Eastern Idaho District Engineer Jason Minzghor.
“The Thornton project will greatly enhance safety and mobility in eastern Idaho area, and most importantly, saves lives.”
The opening of the new Thornton Interchange in eastern Idaho south of Rexburg marked the culmination of more than a decade of U.S. 20 safety improvements. Thornton was the last of seven new interchanges built in a 34-mile stretch of U.S. 20 between Idaho Falls and Sugar City to improve access management and traffic flow for greater highway safety and mobility.
Watch the video of the Thornton project below.
Despite traffic volumes more than doubling, these improvements drastically decreased serious-injury crashes and fatalities. In addition, several money-saving innovations and technological advances saved at least $450,000.
“Providing the contractor with a 3-D model for the Thornton Interchange and requiring them to use automated grade control during construction shortened the required construction time and reduced the impact to traffic through the busiest part of the summer,” said ITD District 6 Engineering Manager Wade Allen.
This marks the fourth Idaho project to advance to the national People’s Choice stage of the America’s Transportation Awards since 2013.
The Idaho Transportation Department is committed to safety for all members of the public — even for the smaller, younger members of our communities. Most school zones have been vacant for the past few months – but that’s all changing. Here are some back-to-school safety tips from ITD:
