Additional closure planned next week for Interstate 84 Exit 201 near Kasota

Due to unexpected weather impacts, all ramps at Interstate 84 Exit 201 and Idaho Highway 25 underneath the interstate will be closed Tuesday and Wednesday (June 1 – 2) to allow for crews to complete work on the roadway.

“We had planned for this phase of construction to be finished by the end of May, but rain in the region delayed our original timeline,” ITD Project Manager Sam Purser said.

The roadway will remain open through Memorial Day weekend, but drivers on I-84 will need to use Exits 194 or 208 during the closure next week. County roads will not be affected.

This is part of a larger project to resurface eight miles of ID-25 from the I-84 interchange to Paul in order to provide a better driving surface for motorists and help extend the life of the roadway.

“We appreciate the patience of drivers as we work to complete construction,” Purser stated. “Even with this minor setback, we still anticipate the project to be complete by late summer.”

Work to begin next week on US-93 in Lincoln County

Construction is expected to begin Tuesday (June 1) on a pavement restoration project near Shoshone. Throughout the summer, crews will rehabilitate the base and resurface the roadway to provide a smoother and safer driving experience for motorists.

“We will begin work on the east side of Shoshone and then continue toward Marley for approximately 12 miles,” ITD Project Manager Tom Logan stated. “This project will use a combination of new and existing roadway materials to stabilize and extend the life of the highway.”

The E 20 North intersection will also be reconstructed as part of this project to improve safety and curves will be upgraded and realigned to meet current standards where necessary.

While crews are on site, the roadway will be reduced to a single lane – Monday through Friday, 7 a.m. to 5 p.m. with the possibility of some work occurring on Saturdays. Flaggers and pilot cars will be present to direct traffic through the work zone. Motorists are advised to slow down and watch for workers and heavy equipment in the area.

Knife River Corporation is the primary contractor on this $7 million project that is expected to be complete in September.

Memorial Day weekend begins the “100 Deadliest Days” on Idaho roads

This Memorial Day weekend, the Idaho Transportation Department’s Office of Highway Safety (OHS) reminds drivers to take caution during the “100 Deadliest Days” on Idaho roads.

The unofficial start to summer begins the dangerous 100 days between Memorial Day and Labor Day when there is an increase in fatal crashes. Last year, 88 people killed in vehicle crashes in Idaho lost their lives during this time frame.

“These warmer months are dangerous because we typically see more drivers on the road, with teens out of school and summer road trips underway,” said OHS Manager John Tomlinson. “We also expect busier roads as COVID restrictions lift and Idahoans feel more confident and eager to get back on the road and travel.”

But it’s not the time to relax behind the wheel. Distracted driving, impaired driving, and aggressive driving also have large impacts on crashes in the summer.

“Whether you are on vacation or just driving your regular commute, it’s always important to make safe decisions while driving. Stay focused and drive engaged, plan for a sober ride, and make sure you buckle up,” Tomlinson said.

Memorial Day weekend also coincides with the national Click it or Ticket seat belt campaign. Law enforcement officers across Idaho are partnering with OHS to participate, issuing citations to those not wearing their seat belt.

“Buckling up is the easiest thing you can do to protect yourself during a crash. It increases your odds of surviving by 50 percent,” Tomlinson said. “We want everyone to get to their destination safely this summer. Take care of yourself and the people you care about by wearing your seat belt and driving well every trip.”

OHS will continue to team up with law enforcement agencies throughout the 100 Deadliest Days to also target impaired drivers and aggressive drivers.

ID-55 Smiths Ferry project transitions to summer work schedule

Spring construction is wrapping up on Idaho Highway 55 between Smiths Ferry and Rainbow Bridge. Thursday, May 27th marks the last day of planned full road closures until September. Friday through Monday during the Memorial Day weekend, both lanes of the highway will be open. Then Tuesday, June 1st, our summer construction schedule begins.

This project will help improve safety and mobility for drivers by widening shoulders, minimizing roadway curves, and installing guardrail in certain locations.

“Our spring construction started in mid-March, and with full road closures Monday through Thursday from 10 a.m. to 2 p.m. crews were able to safely blast rock away from the hillside,” said Project Engineer Alex Deduck. “In two and a half months crews excavated and removed nearly 55,000 cubic yards of material, that’s more than 4,500 truckloads. We’re close to a third of the way through the project now and appreciate everyone’s patience and cooperation as we make this a safer drive.”

Crews will continue their work on the highway this summer. June 1 through Labor Day drivers should plan for one-lane alternating traffic day and night Monday through early Friday morning. Both lanes will be open on weekends Friday through Sunday to accommodate busy summer travel.

Work is expected to begin Tuesday, June 1 on US-30 in Gooding County. This project will improve approximately eight miles of highway between Bliss and Hagerman.

During construction, crews will first resurface the highway and then apply a sealcoat to protect the new surface and provide better traction for drivers.

“This work will improve the highway and create a better driving experience for motorists,” said ITD Project Manager Travis Hitchcock. “In addition to roadway work, crews will also replace guardrail along the Bliss Grade to improve safety in the area.”

Construction will last through mid-July. Motorists should anticipate short delays and watch for the presence of flaggers or pilot cars to guide them through the one-lane work zone during working hours. Crews are expected to be on site every weekday from 7 a.m. to 8 p.m.

Knife River is the primary contractor for this $2.5 million project.

Work to begin next week on Idaho Highway 25 near Eden and Hazelton

Construction is expected to begin Tuesday (June 1) on Idaho Highway 25 in Jerome County. This work will rehabilitate the roadway from milepost 18, approximately four miles west of Eden, to Interstate 84.

“This project will encompass approximately 13 miles of ID-25,” ITD Resident Engineer John Baxter stated. “Although our work zone will be near Eden and Hazelton, construction operations will not occur within the communities.”

Construction will involve pulverizing the surface of the roadway, adding cement and then compacting materials before placing a new surface on the highway. This will reinforce the existing base and extend the life of the roadway.

While work is underway, the highway will be reduced to a single lane. Motorists are advised to watch for flaggers and pilot cars that will be present to direct traffic through the work zone.

This $3.9 million project is expected to be complete late summer. The primary contractor is Western Construction, Inc.

Travel advisory: Motorists should plan for multiple construction projects on U.S. 95 and ID-55 between the Treasure Valley and West Central Mountains destinations

Cars stopped by flagger on Idaho Highway 55

As summer travel heats up the Idaho Transportation Department wants motorists to prepare for short delays on U.S. Highway 95 and Idaho Highway 55 as several construction projects will be ongoing between the Treasure Valley and popular destinations, such as Cascade, Council, New Meadows, and McCall.

Each project will have its own timeline and unique impacts to travel. Each one listed below is linked to the project webpage, which provides additional information.

Construction of these projects will preserve and enhance the safety, mobility, and economic opportunity on our state highway system.

“We’ve designed these projects to limit impacts to the traveling public, especially the during heavy weekend travel periods,” said Jason Brinkman, ITD Engineering Manager. “However, we still encourage motorists to plan ahead, exercise patience, pay attention, and follow the posted signs in the work zones.”

The Department also encourages motorists to check the latest conditions and travel impacts before leaving by checking Idaho 511.

ITD doubles summer flagging resources at Idaho Highway 55 and Banks-Lowman Road to aid safety and mobility

Intersection of ID-55 and Banks-Lowman Road

The Idaho Transportation Department’s Southwest Idaho Office will double the number of days flagging will be conducted at the intersection of Idaho Highway 55 and the Banks-Lowman Road, which can see significant congestion during summer Sundays.

The Department will deploy flaggers on the six weekends this summer anticipated to have the highest number of travelers at the intersection. Historically, flaggers were deployed for the three summer holidays, Memorial Day, Independence Day, and Labor Day. Using historical data and partnering with local event organizers, ITD is changing which days flaggers will mobilize in order to target the busiest days. The current schedule for flagging is:

June 20th
July 5^th(Independence Day)
All remaining Sundays in July (11, 18, 25)
September 6^th (Labor Day)

“We removed Memorial Day from our flagging schedule after we looked at years of travel data,” said Caleb Lakey, District Administrator of ITD’s Southwest Idaho Office. “We confirmed the reports of our maintenance staff that there are, on average, more cars on the road any given Sunday in July and the first weeks of August than Memorial Day. A lot of that is weather dependent, and we may still see a lot of people on the road if we have warm temperatures early on.”

ITD urges motorists to still plan for significant travel delays on ID-55 between Boise and Cascade, as well as on the local road, Banks-Lowman Road during summer weekends. Flagging the intersection relieves some congestion on Banks-Lowman Road but also slows traffic on ID-55.

“Ultimately, both highways and the intersection simply reach capacity as everyone who spent the weekend in the mountains returns home to the Treasure Valley,” said Lakey. “I urge those travelers to consider taking alternate routes or making their return outside the peak time of 11 a.m. to 5 p.m. Otherwise, plan to have some delay.”

ITD is partnering with the Western Federal Land Division of the Federal Highway Administration to develop a plan for improvements at this intersection. The project launched in March 2021 and will complete environmental and geotechnical work along with preliminary design options for the intersection improvement. ITD will seek additional funding to finish design, acquire right of way, and construct the improvement.

In addition to the increased flagging days, ITD has placed new advisory signs ahead of the intersection. The new signs will advise slower speeds and alert drivers to the congestion and flagging ahead. These signs will improve the safety of the intersection and the efficiency of deploying the flaggers – a major factor in the department’s decision to increase flagging days.

The 2021 flagging operation is the direct result of robust engagement between ITD and the communities in Boise and Valley County. In fall 2019, ITD held a public meeting in Garden Valley to discuss the challenges of the intersection. Following that meeting, the department formed a community working group which spent 2020 developing this plan.

“I want to thank the community for partnering with us on this situation,” added Lakey. “We all want to see business flourish while preserving the unique beauty of Idaho’s Central Mountains. The impacts of growth in southwest Idaho is felt in every community. The public servants at ITD are doing everything we can to meet the growing needs. All users of the road need to take responsibility to plan ahead, drive well, and make wise decisions.”

ITD encourages those traveling from or through the McCall/New Meadows area to consider using U.S. 95 as an alternate route. Those with trips from Stanley or Lowman should consider using Idaho Highway 21 to avoid the congested intersection.

Be sure to Recreate Responsibly. Pack plenty of water and snacks, ensure your vehicle is well maintained, fill your gas tank before long trips, and take a restroom break before traveling through a remote location. Check out road conditions and travel delays before you leave by downloading the Idaho 511 app, available for Apple and Android devices.

Slide on Idaho Highway 11 near Headquarters to disrupt traffic over Memorial Day Weekend

The slide condition just days after being discovered

The Idaho Transportation Department would like to advise travelers over the holiday weekend of unexpected delays on Idaho Highway 11 near Headquarters. This will impact drivers on their way to popular sites up the North Fork of the Clearwater River and the Grandad Recreation Area.

“Last month we noticed that the shoulder of ID-11 was falling away from the road,” Engineering Manager Bob Schumacher said. “Since then, the northbound lane has sunk further and is now estimated to be an eight-foot drop off.”

*A man stands on the highway where the shoulder is starting to sink on April 16*

*The drop off is now closer to eight feet as of April 23*

The northbound lane of ID-11 is closed, with drivers required to yield to southbound traffic. A drill will be on site today and tomorrow to bore below the highway and into the slope. While boring beneath the highway, flaggers will stop all traffic for approximately 15 minutes at a time. Crews will also install monitoring devices to track further movement.

“We will collect soil samples at various depths,” Schumacher said. “We are looking for layers that appear to be saturated so we can determine the severity of the slide.”

Repairs will then be designed and added to a resurfacing project that was already planned for this summer between Grangemont Road and Headquarters. It is unclear at this time how the repairs will affect the timing and budget of the project.

Drivers should continue to expect at least a lane closure in the area and should check 511.idaho.gov for impacts before traveling.

ITD launches two-week virtual meeting (May 21-June 4) to share next steps for Idaho 16 extension

The Idaho Transportation Department launches a two-week online meeting today (May 21) to share plans for the next phase of extending Idaho Highway 16 through the central Treasure Valley. The meeting will be available from May 21 to June 4 at itdprojects.org/idaho16.

The meeting includes a virtual tour and design plans for the future north-south corridor, which is currently the primary route to Emmett. ITD is extending the corridor 5.5 miles south to connect with I-84.

The extension of Idaho 16 will operate as a high-speed expressway, with limited access on or off it. By 2040, the highway is expected to serve 60,000 motorists each day in the growing area between Ada and Canyon counties.

“This corridor has been in the making for many years and the community has given input at many important stages of this significant highway corridor,” said ITD Program Manager Amy Schroeder. “All of the design plans in this online meeting are consistent with the overall vision and allows ITD to proceed to construction next year.”

Phase 1 of the corridor was completed in 2014 and involved bridging Idaho 16 over the Boise River and connecting U.S. 20/26 and Idaho 44.

On Wednesday, the Idaho Transportation Board approved funding to construct the next phase of the extension. Phase 2, the focus of the online meeting, will build the remaining five miles of highway from U.S. 20/26 to I-84. This includes an interchange with I-84, connections at Franklin and Ustick Roads, and bridge structures over local roads, canals, and a railroad.

The estimated cost of this work is $170 million. It will be funded using bonds and paid off using new sales tax funds approved by the Idaho Legislature in 2021.

“The work we have done on the Idaho 16 corridor in the last few years has prepared us to quickly leverage this new funding stream,” said Schroeder. “We have an obligation to the taxpayer to make the most of the today’s low interest rates and bring needed transportation investments to Idaho quickly.”

The online meeting will include live Q&A sessions from 12-1 p.m. and 5:30-6:30 p.m. on June 2. Alternate versions of the meeting are available for those without Internet access. Please contact ITD at (208) 334-8008 or Idaho16@ITD.Idaho.gov.
