ITD and Idaho State Police lower speed limit in south-central Idaho on stretch of I-84 in construction zone

The Idaho Transportation Department and Idaho State Police will lower the speed limit to 65 mph July 14th in a stretch of Interstate 84 within an active construction zone east of Twin Falls. The reduction is being made to maximize the safety of drivers traveling through the area.

ITD south-central Idaho Traffic Engineer Bruce Christensen stated “speeds are an important factor in any traffic control plan, but motorists putting away distractions and paying attention to the roadway is paramount in keeping our roadways safe.”

“The posted speed limit is a maximum during ideal conditions — it is not meant to replace a driver’s good judgment,” he added.

Work zone speed limits are determined in accordance with federal guidelines set by the Manual on Uniform Traffic Control Devices. Additional factors taken into account when determining speed limits are physical barriers like sight restrictions or curve radiuses, and observed traffic flow.

Lieutenant Robert Rausch, a Deputy District Commander with ISP, said “we are seeing problems related to impatience and inattentiveness when drivers enter a work zone. Motorists are often time driving too aggressively for the area and not affording themselves enough space to safely react to changes in traffic flow.”

“There are a lot of moving parts in a work zone and that’s why drivers need to do everything they can to stay engaged,” said Ken Corder from the Office of Highway Safety. “There are new traffic patterns, heavy machines, and workers in these areas trying to improve our roads—we can do our part to slow down and put away the distractions.”

“The goal of every traffic-control plan is to ensure that traffic flows safely and efficiently regardless of how many vehicles are on the road or the type of vehicle,” said ITD District Engineer Devin Rigby. “If speeds are continually fluctuating, or if traffic comes to a standstill on the interstate, the safety concerns mount.”

Drivers also have an important role to play. The most common contributing factors in Idaho crashes are aggressive driving, distracted driving, and impaired driving — all of which are human-caused. In fact, about 94% of serious-injury crashes are caused by human error.

The time between the Memorial Day and Labor Day weekends are often referred to as the “100 Deadliest Days” because it’s a time of year when deadly crashes tend to spike. As the timeframe indicates, we are currently in the middle of this unfortunate period. According to preliminary reports, there have been at least 40 reported fatalities on Idaho roads since the 2018 Memorial Day weekend began.

“One thing I like to stress during these summer months is for drivers to plan ahead and be prepared,” said Lieutenant Rausch. “Be prepared for the unfortunate event of your vehicle breaking down, plan ahead to ensure you always have a sober driver, and make sure you are never driving drowsy or distracted.”

Construction will begin on Idaho 55 next week (July 16) near McCall

Idaho 55 Zachary to Goose Creek Map

The Idaho Transportation Department will begin a project next week (July 16) to resurface Idaho Highway 55 between New Meadows and McCall and construct a new retaining wall east of Brundage. The project will improve driving conditions and safety on this heavily traveled route.

From July to late August, crews will work between Zachary Road in McCall and Goose Lake Road near Brundage. View the postcard for details.

In order to keep traffic moving during the busy summer season, crews will work from 12 a.m. Monday to 12 p.m. Friday. All lanes will be open on weekends.

During the week, ID-55 will be reduced to one lane both day and night with a pilot car directing traffic. The speed limit will be reduced and 12-foot width restrictions will be in place.

“This will be a tight construction zone and we are asking for drivers’ patience during the work week. Please slow down in the work zone and pay close attention to signage, as crews will be working close to traffic,” said ITD Project Manager Jim Hoffecker.

Construction will move to the area between Goose Lake Road and Goose Creek Grade in late August. The project is expected to be completed this fall.

Nampa to Marsing, ID-55 preservation projects begin after 4th of July Holiday week

Map of seal coat project on ID-55 from Nampa to Marsing

A pavement rehabilitation project between Nampa and Marsing is scheduled to begin July 9 and conclude in late July/early August. Work will seal the pavement and extend the life of the roadway.

The first phase, a six-mile micro-seal from Nampa-Caldwell Boulevard to Farmway Road, will occur in the evening (10 pm – 5 am). Work is expected to conclude the week of July 16.

The second phase, an eight-mile chip-seal from Farmway to the Snake River Bridge at Marsing, will occur during daylight hours. Work is expected to conclude in late July.

During both phases, motorists can expect reduced speeds and up to 15-minute delays as traffic will be periodically reduced to one-lane with a pilot car guiding traffic. Where work is occurring, intersections will be controlled by flaggers with minimal delays. Motorists are encouraged to drive with caution through the work zone.

Schedules are subject to change. The contractor is permitted to work weekends. For up-to-date construction information, visit

Holiday Travelers are Reminded to Drive Well

Independence Day is nearly and for many of us that means fireworks, barbeques and road trips.

As Idahoans prepare for their holiday travels, the Idaho Office of Highway Safety reminds them to be engaged behind the wheel.

“It’s an exciting time of year,” said Highway Safety Manager John Tomlinson. “There is so much going on both inside and outside of the car that it really takes a conscious effort to stay focused.”

The busy travel holiday comes in the midst of the 100 Deadliest Days on Idaho roads. Since the Memorial Day weekend there have been at least 30 people killed in traffic crashes.

This year, is expected to be a busy one for people looking to get away for the Fourth of July both nationally and right here in Idaho. AAA predicts 47 million people will travel for the holiday, including a quarter million Idahoans.

“As with the national totals, we expect about a five percent increase in auto travel and an eight percent increase in air travel,” said Matthew Conde, public affairs director for AAA Idaho. “July 3 is expected to be the busiest day, particularly as vacationers mingle with commuters in the afternoon.”

In addition to additional motorists being on the roads, there will also be an increased presence from law enforcement agencies taking part in a statewide effort to get drunk drivers off the road.

“A lot of holiday cookouts involve alcohol and we just don’t want to see people get behind the wheel after a few drinks,” Tomlinson said.

“We also encourage careful and responsible celebration – alcohol does not mix well with fireworks, boating, or driving,” added Conde.

Highway sealcoats to take place this July throughout north-central Idaho

To extend the life of previously completed highway projects, sealcoats will be applied to several highways throughout the region starting July 9. The newly-treated surface helps preserve the pavement and provides for better vehicle traction.

When sealcoats are applied, roadways will be reduced to one lane. Motorists should anticipate short delays and watch for the presence of pilot cars.

Sealcoating is a roadway surface treatment best applied during the hot and dry months of summer when chips of aggregate will properly adhere to an oil layer deposited on the highway.

Drivers are cautioned to slow down and pay attention within the work zones, as chips placed during the sealcoating process have the potential to cause windshield damage.

Crews will begin applying sealcoats in the order below:

  • July 9: Idaho Highway 8 from Moscow to Troy (11.7 miles)
  • July 12: Idaho Highway 8 from Deary to Bovill (10.2 miles)
  • July 16: Idaho Highway 11 from Greer to the top of Greer Grade (8 miles)
  • July 20: Idaho Highway 11 from Weippe to Grangemont Road (11 miles)

All sealcoats are expected to be completed by the end of July.

Landslide repairs to ID-5 near Plummer will start next week

Repairs to Idaho Highway 5 near Plummer will begin the week of July 9.

Construction will fix damage caused by a March 2017 landslide at milepost 5.8. Crews will remove and replace unstable material below the highway. New material is designed to anchor the hillside and prevent future landslides.

Travelers can expect short delays while flaggers and signals guide traffic through the one-lane work zone. Crews will typically be on site every day but Sunday.

Construction will last two months. Check 511 for the latest traffic updates.

Paving on US-12 in north-central Idaho to start next week

Fifty miles of US-12 will be paved this summer to improve mobility and safety in the area, with work set to start on the first section during the week of July 9.

The 27-mile section between Tumble Creek and Saddle Camp Road will be resurfaced first, followed by the 23-mile section between Warm Springs and the Idaho-Montana border, which is expected to begin in August.

The highway will be reduced to one lane during both paving projects, with flaggers and pilot cars in place to guide traffic through work zones. A daytime shuttle service will be provided to safely transport bicyclists through the longer work zones. Once a schedule is finalized, it will be published on the project website and the corridor newsletter.

Paving operations are anticipated to take place at night to minimize impacts to the traveling public, but travelers should expect flagging operations and delays during the day.

During construction, travelers on US-12 between Lowell and the border should plan for delays up to two hours, as other projects to replace Fish Creek and Maggie Creek bridges are already underway. Due to the remote location and length of the work zones, travelers are also advised to fill up their gas tanks before driving through construction.

Construction for all US-12 projects will conclude this summer, bringing nearly $17 million of much-needed infrastructure and safety improvements.

Highway sealcoats to take place this July throughout North Idaho

To extend the life of previously completed highway projects, sealcoats will be applied to several highways throughout the region starting the week of July 9.

When sealcoats are applied, roadways will be reduced to one lane. Motorists should anticipate short delays and watch for the presence of pilot cars.

Sealcoating is a roadway surface treatment best applied during the hot and dry months of summer when chips of aggregate will properly adhere to an oil layer deposited on the highway. The newly-treated surface helps preserve the pavement and provides for better vehicle traction.

Drivers are cautioned to slow down and pay attention within the work zones, as chips placed during the sealcoating process have the potential to cause windshield damage.

Sealcoating projects scheduled to occur this summer along with their anticipated start date, location and length are as follows:

  • July 9: Idaho Highway 3 — approximately 31 miles from the Coeur d’Alene River Bridge to the Canyon Creek Road area
  • July 16: Idaho Highway 58 — approximately 3 miles from the Washington border to the US-95 junction
  • July 17: Idaho Highway 54 — approximately 3.5 miles from the Goodhope Road traffic circle through Farragut State Park
  • July 18: US-95 — approximately 6 miles from Fawn Lane to the Idaho Highway 1 junction
  • July 19: US-95 — approximately 19 miles from Samuels Road to Tamarack Street

Crews will repaint the highways after sealcoating. All work is expected to be completed by early August.

Transportation department seeks public comment in July on planned projects

The Idaho Transportation Department is seeking public comment from July 1 – July 30 on the FY 2019-25 draft of the Idaho Transportation Investment Program (ITIP), and all transportation stakeholders are encouraged to participate.

The ITIP is a seven-year “roadmap” for planning and developing transportation projects, including:

–  Highways and bridges
–  Bicycle and pedestrian facilities
–  Highway safety
–  Railroad crossing safety
–  Airports
–  Public transportation
–  Transportation planning
–  Freight

The transportation department is offering an online, interactive map that allows users to choose specific project categories, and learn about work that is planned for the area of Idaho they’re interested in. It’s called the Idaho Transportation Project Map.

View the draft ITIP and interactive map. 

The draft ITIP document lists projects by highway route and location, identifies projected years for right-of-way acquisition, preliminary engineering, construction and estimated project costs. It also lists local construction projects that are federally funded.

The projects start in 2019, and go through 2025.

Public comments will help the department determine if proposed projects meet the department’s three main objectives of improving safety, mobility and economic opportunity.

Production of the ITIP is a year-round process that relies on input from elected officials, citizens, tribal governments, other state and federal agencies, Idaho’s metropolitan planning organizations, the Local Highway Technical Assistance Council, and other interested organizations.

Comments can be e-mailed to or mailed to ITIP – Comments, Attn: Adam Rush, P.O. Box 7129, Boise, ID  83707-1129. Paper or CD copies of the ITIP will be provided upon request by contacting Rush at (208) 334-8119 or by e-mail at

A request for a paper copy or CD also can be mailed to: Idaho Transportation Department, Adam Rush, P.O. Box 7129, Boise, ID  83707-1129.

A printed copy can be reviewed at any of ITD’s district offices in Coeur d’Alene, Lewiston, Boise, Shoshone, Pocatello and Rigby.

All comments on the draft will be reviewed after July 30. After approval by the Idaho Transportation Board, the ITIP is submitted to the Federal Highway Administration, the Federal Transit Administration and the Environmental Protection Agency.

Single lane closure on eastbound I-84 Sunday July 1

Cloverdale Lane Closure

The Idaho Transportation Department will close the left-most lane of eastbound Interstate 84 beneath the Cloverdale Overpass Sunday, July 1. This will allow crews to perform work in preparation for replacing the damaged bridge.

Crews will drill beneath the existing bridge to test the soil composition. This will inform what treatment is needed for the foundation of the replacement bridge for Cloverdale Road. The replacement, currently being designed by ITD engineers will feature four 11-foot travel lanes, 5.5-foot raised bike lanes, and 7.5-foot sidewalks.

The single-lane closure is expected to begin early Sunday morning and stay in place for most of the day.

Drivers are encouraged to use caution in the work zone. For updated information on traffic impacts on the State Highway System, please visit 511 online at
