After the next two weeks, drivers will no longer be slowed by construction to build a passing lane on U.S. Highway 95 between Culdesac and Winchester as the project shuts down for winter.

The original schedule included the opening of a new passing lane for southbound drivers in November, but challenges with environmental resources has delayed completion.

A few months into construction the contractor discovered important sensitive resources within the project limits and stopped all work on that portion of the project.

The Idaho Transportation Department works with the Nez Perce Tribe and other entities on certain projects to avoid, minimize or mitigate impacts to these sensitive resources. On some projects with potential cultural resources, the department hires resource monitors to observe construction activities.

During construction, monitors identified sensitive resources and stopped work in that area until further investigation could be completed, and mitigation could be approved. At this time, the department is still working with the Tribe to finish the investigation, so construction in the area is not yet allowed to proceed.

Then in late August, while the contractor was building a retaining wall near Lapwai Creek, some steelhead trout were stranded and subsequently died. Steelhead trout in the region are listed as threatened under the Endangered Species Act.

Construction plans were approved by the National Marine Fisheries Service (NMFS), an agency of the National Oceanic and Atmospheric Administration, and the project was approved for some fish being harmed or killed, though to a lesser extent.

“After the incident this year, we partnered with the Tribe and the NMFS to revise the plan for the remainder of construction. We will also discuss the remainder of work so that the fish are better protected when we resume work,” Resident Engineer Curtis Arnzen said.

Arnzen believes collaboration on this project will improve construction practices for future projects as well.

“Given the environmental challenges of the project, we do not know exactly when construction will begin next year, but we hope to start next July, which is a good time of year for in-water work in Lapwai Creek relating to the protection of threatened fish,” Arnzen said.

This project is part of a corridor-wide plan to finish building an 11-mile passing lane in Culdesac Canyon to provide safer opportunities for drivers to pass.

Sept. 12 update:

Rock scaling will begin Tuesday, September 20, at the top of White Bird Grade to stabilize the slope above U.S. Highway 95. Work over the next several weeks will intermittently affect the highway.

Scaling involves knocking down loose debris proactively, with rocks falling from the hillside down to the road. Specialized equipment will excavate rock at the top and flatten the slope.

“At least for the first day, we’ll have flaggers there to stop all traffic for 20 minutes at a time while workers are scaling,” Operations Engineer Jared Hopkins said.

Work is scheduled Monday through Saturday, with construction starting each day at daybreak.

“As work continues, we may allow traffic to flow without being stopped during work if it is safe to do so,” Hopkins said.

Metal containers that have been shielding drivers since the rockslide in May at this location will be shifted back on to the highway. The passing lanes will be closed earlier, forcing drivers to merge sooner. When crews are not on site, traffic will flow freely over the hill with one lane in each direction.

Drivers are encouraged to check road conditions at 511.idaho.gov.

May 11 update:

All lanes on U.S. Highway 95 are now open after the Idaho Transportation Department removed debris from a rockfall on Monday morning and placed barriers to protect drivers.

One lane had remained open immediately following the rockfall. New railroad containers have taken the place of concrete rail to offer better protection should more rocks come down.

“More rocks fell down this morning. The slope is not stable,” Operations Engineer Jared Hopkins said. “This will not be a quick fix.”

The department is working to secure an emergency contract to further assess conditions and then likely use specialized equipment to scale the slope. Scaling involves knocking down loose debris proactively.

May 9 update:

Following persistent rain over the last week, a rockfall blocked lanes this morning on U.S. Highway 95 at the top of White Bird Grade south of Grangeville. The highway remains reduced to one lane.

Rocks ranging from 6 inches to 6 feet wide blocked the southbound lane around 10 a.m. Crews immediately responded by alternating northbound and southbound traffic and hauling away debris.

Rocks continued to fall down the slope, prompting the Idaho Transportation Department to place concrete rail to protect drivers. A spotter will watch the hillside through the night, ready to close the highway at a moment’s notice. Flaggers will control traffic through tonight and likely tomorrow night.

“This happened during blue skies,” Operations Engineer Jared Hopkins said. “Just a reminder that sometimes it takes a bit for rain to seep into a slope and make it unstable.”

Experts will continue to monitor the site. The department is arranging for large railroad containers to be placed at the edge of the highway to block any future rockfall.

“We will let this settle overnight, but in the morning our goal is to continue removing debris,” Hopkins said. “Once larger barriers are in place, we’re hopeful to have one lane in each direction while we identify a long-term solution.”

The department is also working to secure an emergency contract to use specialized equipment to scale the slope, a process that involves knocking down loose debris proactively.

BOISE – The U.S. Department of Transportation’s Federal Highway Administration (FHWA) today announced the immediate availability of $3 million in “quick release” Emergency Relief (ER) funds to help the Idaho Transportation Department (ITD) repair roads and bridges damaged by recent floods.

“The emergency funding we’re announcing today will help the people of Idaho recover from these devastating floods and safely reopen their roads and bridges as quickly as possible,” said U.S. Transportation Secretary Pete Buttigieg.

Extreme moisture, runoff and flooding occurred following the heavy rains in NezPerce and Idaho counties causing significant damage, as well as creating dangerous travel conditions in the North Central and Northeast regions of the state beginning June 10, 2022. Numerous roadways in the area were obstructed from the flooding. Idaho Governor Brad Little issued a disaster declaration on June 22 to assist with response and repair efforts.

“Today’s funding represents a down payment on our federal commitment to ensuring roads and bridges in Idaho damaged by the flooding are repaired as quickly as possible,” said Deputy Federal Highway Administrator Stephanie Pollack. “The flooding has interrupted daily life in communities in the region, and we hope that by restoring vital transportation links people can regain a sense of normalcy.”

Initial flooding closed the northbound lane of US-95 four miles south of Lapwai. Crews worked diligently to reopen two lanes with an asphalt surface as soon as possible and committed to start refocusing on more permanent repairs later this summer.

These “quick release” funds will go toward emergency repair work and operations to maintain traffic flow throughout the disaster. Damaged roads include US-95, Gifford-Reubens Road, Southwick Road and Webb Road in Nez Perce County as well as Toll/Clear Creek Road in Idaho County.

FHWA’s ER program provides funding for highways and bridges damaged by natural disasters or catastrophic events. These funds are an initial installment of funds used to restore essential traffic and to limit further highway damage, which can help long-term repair work begin more quickly.

The funding announced today adds to the more than $70 million recently provided to the Montana Department of Transportation, the Wyoming Department of Transportation, the U.S. Department of Interior’s National Park Service for Yellowstone National Park and the U.S. Department of Agriculture’s Forest Service for Custer Gallatin National Forest to repair flood damage.

ITD is asking for input on the just-released draft Idaho Transportation Investment Program (ITIP). The 2023-2029 ITIP is a seven-year master plan of the state’s transportation improvement projects. Everyone is encouraged to participate starting in July.

Projects can range from large-scale interstate improvements to smaller projects like the installation of a new guardrail. In all, the draft ITIP includes projects in all 44 counties and all modes of transportation. Projects were selected based on technical data, as well as input from local officials and residents.

A complete breakdown of the draft plan can be found at itd.idaho.gov/funding.

Projects newly funded in North Central Idaho with this update include:

• Resurfacing U.S. Highway 12 from Greer to Kamiah in 2024.
• Extending the northbound passing lane on U.S. Highway 95 over Crooks Hill north of Viola in 2029.
• Modifying curves and adding guardrail to US-95 from Rapid River to Riggins in 2029.

Construction originally planned for this summer on US-12 between Orofino and Greer has been combined with a 2023 project to repave State Highway 11 from the top of Greer Grade to Weippe. Both projects will be jointly advertised this fall, with some construction possible before winter.

Comments will be taken from July 1-31 and can be e-mailed to ITDcommunication@itd.idaho.gov or mailed to:

ITIP – Comments
Attn: Office of Communication
P.O. Box 7129
Boise, ID  83707

Paper copies of the ITIP will be provided upon request by contacting the Idaho Transportation Department (208) 334-8119.

All comments will be reviewed, incorporated into the ITIP where appropriate, and responses will be sent in September once the comment period has ended.

After approval by the Idaho Transportation Board in September, the ITIP will then be submitted to the Federal Highway Administration, the Federal Transit Administration, and the Environmental Protection Agency in October.

June 15 update

Both lanes of U.S. Highway 95 south of Lapwai at milepost 296 are now open following repairs to damage caused by flooding earlier this week.

Floodwaters from Lapwai Creek first began eroding the northbound lane on Monday morning, and the Idaho Transportation Department reduced traffic to one lane. Repairs began later that day, with crews bringing in rock to replace what was lost and prevent further damage.

“We are happy to return US-95 to normal condition,” Operations Engineer Jared Hopkins said.

Traffic impacts and highway conditions are available 24/7 on 511.idaho.gov.

June 14 2022 update

US-95 south of Lapwai remains partially closed due to flood damage

One lane of U.S. Highway 95 remains closed south of Lapwai at milepost 296 due to flood damage.

“With floodwaters receding and drier days in the forecast, we feel we are past the emergency,” Operations Engineer Jared Hopkins said. “Yesterday, we rushed to get an excavator on scene to start placing large boulders against the bank to save what remained of the northbound lane of US-95. In one spot, it had washed away to the center.”

Watch a video of the flooded creek.

Watch a video of traffic moving around the damaged section.

Crews aim to finish placing rock and reopen both lanes of the highway by the end of the week.

“We are working hard to have two lanes open with an asphalt surface as soon as we can,” Hopkins said. “Then we’ll start focusing on more permanent repairs later this summer.”

Water over the roadway has also been reported on State Highway 6 between Potlatch and Deary. Before traveling drivers should check conditions on their routes at 511.idaho.gov.

June 13 2022

Flooding closes one lane of US-95 south of Lapwai, more rain in the forecast

Earlier this morning, the Idaho Transportation Department closed one lane of U.S. Highway 95 four miles south of Lapwai at milepost 296 due to flooding.

“Flooding of Lapwai Creek has washed away the shoulder next to the northbound lane and may be undermining the highway,” Operations Engineer Jared Hopkins said. “Closing that portion of the roadway is necessary to ensure safety.”

More rain is expected today and tonight.

“Until the rain stops and the creek drops, there’s nothing we can do except monitor the flooding and close the highway if necessary,” Hopkins said. “We want to put drivers on notice that we may need to shut it down.”

Before traveling drivers should check conditions on this highway and others at 511.idaho.gov.

Preliminary work to expand U.S. Highway 95 on a new alignment from Thorn Creek Road to Moscow began last week, with crews mobilizing into the middle segment and beginning survey.

The project will transform 6.5 miles of US-95, shifting it less than a mile to the east and expanding it from two to four lanes, enhancing safety for all users. Work this year will include earthwork and two new bridges over Eid Road.

Only some of the construction will be visible from the highway. Drivers should expect contractors’ vehicles and equipment near Zeitler Road throughout the next several months.

“This is the last two-lane section between Moscow and Lewiston,” ITD Project Manager Howard Cooley said. “The new route will tie in at Reisenauer Hill and be safer by featuring flatter grades, fewer approaches and less severe curves.”

US-95 is Idaho’s only north-south continuous highway, connecting travelers and commerce across the state.

Update as of May 11: The blast has been rescheduled for next week. Up to three blasts are expected in the next two weeks, with each lasting up to one hour. 

The first blast of the season is expected to close U.S. Highway 95 south of Culdesac for up to one hour starting 6 p.m. on Wednesday.

Blasting this spring will make room for a new passing lane for southbound drivers. Blasts will generally be timed to avoid peak travel times and require a one-hour closure.

“We are expecting more blasting this month, but the schedule will be sporadic,” Resident Engineer Curtis Arnzen said. “Generally, there will be less blasting this year compared to previous work in the canyon.”

Construction this year will add 2.3 miles of passing lane and is part of a series of projects to add an 11-mile passing lane in Culdesac Canyon.

Crews will also replace the culvert for Rock Creek. For most of construction, drivers can expect all existing lanes to remain open. The contractor may reduce the highway to one lane at night.

Drivers should pay attention to signs in the work zone to learn about the timing of the next blast or check 511.idaho.gov. Work is scheduled to end by early November.

 

After careful consideration, the Nez Perce Tribe (NPT) and the Idaho Transportation Department (ITD) delayed advertising the project to build a new interchange at the east entrance of Aht’Wy Plaza for construction.

“Our goal was to start construction on the interchange this spring, but prices on materials have compelled both parties to step back and consider how to move forward,” ITD District Engineer Doral Hoff said.

Construction costs have increased with rising prices for essential materials like steel, concrete, asphalt and fuel. While the project will still make use of $19 million in grant funding, costs have escalated since the grant was announced in September of 2020.

In response to price increases, the NPT has contributed an additional $1.2 million to construction, but more recent estimates call for another $5.5 million. To cover this increase, the project was submitted for additional federal funding with recipients announced later this summer.

Advertisement will be delayed until this summer, at which point the NPT and ITD will decide how to proceed. If the project is awarded more money, construction could begin late this summer.

“The Tribe and ITD are still committed to working together to see this project through, despite any funding challenges,” NPT Transportation Manager Mary Beth Frank Clark said.

This interchange project is not the only project to be delayed due to cost increases—last week the Idaho Transportation Board rejected the bid for the project to resurface eight miles of US-12 between Orofino and Greer. That project will not be advertised again until fall for construction next spring.

“Inflation and supply chain issues continue to make construction a challenging time for transportation departments across the nation,” Hoff said. “At ITD we budget increases for every project every year due to inflation, but we were not expecting such severe circumstances.”

ITD staff will continue to monitor guidance from national transportation economists and results from bid openings to avoid delaying additional projects. The department is also partnering with the Associated General Contractors of Idaho to limit the effects of inflation.
