Repairs to Greer Bridge begin next Monday

Repairs to the Greer Bridge will start Monday, July 22, with temporary signals impacting both Idaho Highway 11 and US-12 traffic until construction is complete in late September.

One lane at a time will be open over the bridge, and drivers may experience up to 15-minute delays.

This summer the driving surface will be improved, and supporting beams will be painted to protect them from rusting and to keep the bridge in service longer.

The structure was built in 1954.

Transportation department seeks public comment on planned projects in North-Central Idaho

Two cranes help with 2019 construction of a passing lane in Culdesac Canyon just north of Winchester.

The Idaho Transportation Department is seeking public comment from July 2 – August 2 on the FY 2020-26 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 2020, and go through 2026. Notable upcoming projects in North-Central Idaho include:

  • US-95 expansion between Thorncreek and Moscow beginning in 2020, pending land acquisition and a permit from the Army Corps of Engineers. More information is available at itdprojects.org/us95thorncreektomoscow.
  • US-95 expansion through Culdesac Canyon. Ongoing work will be followed with construction of the final two phases in 2023 to add a passing lane between Winchester and Culdesac. More information is available at itdprojects.org/us-95-culdesac-canyon-passing-lane.
  • Portions of US-12 between Kooskia and Montana that were not addressed with 2018 construction will be resurfaced and possibly widened with the earliest project scheduled for 2022.

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 adam.rush@itd.idaho.gov 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 adam.rush@itd.idaho.gov.

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 Aug. 2. 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.

Extended closure on US-95 at Culdesac Canyon expected tonight

Blasting and equipment removal are planned near ongoing work to add a passing lane in Culdesac Canyon on US-95, requiring intermittent, hours-long closures from 7 p.m. tonight to 4 a.m. tomorrow morning (July 2).

A blast is scheduled to start at 7 p.m., during which the road will be closed and not reopen until after debris is cleared, approximately 1.5 hours later.

Between 10 p.m. and 4 am, drivers can expect longer closures as crews remove a crane that fell Saturday afternoon onto US-95. Traffic will be allowed to pass around midnight, but between midnight and 4 a.m., drivers may not be able to pass through the area for up to three hours. No detours will be posted.

The crane fell while installing a temporary bridge. No one was injured during the incident, and crews were able to open US-95 to one lane later that afternoon.

Blasting operations are planned for the next two years in this area, with updates posted to 511.idaho.gov and displayed on message signs near the project. Traffic impacts are not expected July 3-5, though crews will be working in the area.

US-95 White Bird Grade paving begins next week

Resurfacing of White Bird Grade on US-95 is planned to start next week, with work beginning as early as Monday, June 24.

More than seven miles of the south side of the grade will be paved, with one lane open in each direction until construction is completed in August.

Work is expected during the day, with some weekend shifts possible. Paving is expected to start at the top of the grade and progress downhill.

Three runaway truck ramps will also be improved, requiring temporary closures. Larger vehicles will be notified at the top of the hill if any ramps are closed before descending.

Earlier this year, crews updated guardrail and signage in the area. More information on construction projects is available at itdprojects.org.

ID-6 curve realignment near Potlatch begins next week

ID-6_Potlatch curves

Starting next week, contractors will begin constructing temporary lanes for a project to replace a bridge and realign curves on one mile east of Potlatch on Idaho Highway 6.

Work will start near Gold Creek as crews build temporary lanes around the existing structure to be used during its replacement. These temporary lanes will be in place from late June until the bridge is completed in late October.

Once the temporary lanes are completed, crews will start moving dirt for realignment of the highway. Work will progress from town towards the bridge, with most earthwork occurring off the existing road.

Speed will be reduced during construction due to trucks entering and exiting the highway and the temporary alignment over Gold Creek. Flaggers will periodically reduce the highway to one lane. Two lanes will be open outside of work hours.

Work to widen a sharp curve in Potlatch will begin in early October.  Drivers should expect only one lane with flaggers during the day and two lanes with gravel surfaces during non-working hours.

Construction is set to be complete by the end of October. Learn more at itdprojects.org/id6potlatchcurves.

Open house June 11 for Clearwater Memorial Bridge in Lewiston

US-12 crosses the Clearwater River.

The public is invited to an open house on Tuesday, June 11 to learn about plans to widen and repair the Clearwater Memorial Bridge.

The open house will be at the Red Lion Hotel (621 21st Street) from 4 p.m. to 7 p.m. Community members will have an opportunity to learn about the project, which is scheduled to start construction in 2023.

“The existing structure was built in 1951, and some of its components are nearing the end of their service life,” ITD project manager Curtis Arnzen said. “ITD is making major plans to improve the bridge to ensure that it will serve the region for many years into the future.”

Plans include widening the shoulders and sidewalks over the structure, as well as creating a wider median to divide lanes.

For more information and to comment online after the meeting, visit itdprojects.org/us12memorialbridge.

Testing scheduled in May and June at Clearwater Memorial Bridge

US-12 crosses the Clearwater River.

The Idaho Transportation Department has scheduled a series of tests in May and June near the Clearwater Memorial Bridge on US-12 in Lewiston. The tests will help develop plans to widen and repair the bridge, with work currently scheduled in 2023.

This weekend a hole will be drilled into the southeast corner of the bridge to examine soil quality, requiring the closure of the sidewalk.

Shortly after, river users will see a barge next to the bridge. From the barge crews will analyze the riverbed to help determine the best way to increase the bridge’s weight capacity. This testing will not affect recreational activities on the Clearwater River.

The existing structure was constructed in 1951, and some of its components are nearing the end of their service life.

“ITD is making major plans to improve the bridge to ensure that it will serve the region for many years into the future,” ITD project manager Curtis Arnzen said. “This project will improve the area’s safety, functionality and economic opportunity.”

An open house will be held in June to introduce the project and gather comments.

North Idaho bridges set for replacement this year, starting with Butcher Creek on ID-13

Bridge over Little Hangman Creek on ID-60 is one of seven structures being replaced from 2019 to 2021.

Picture of bridge at Little Hangman Creek. 

Update as of May 21: Contractors now anticipate starting at Little Hangman Creek on Wednesday, May 29 and possibly starting at Butcher Creek in July. 

Four bridges and three culverts from Grangeville to the Canadian border are scheduled for replacement over the next three years, beginning with Butcher Creek on Idaho Highway 13 near Grangeville.

Construction on Butcher Creek will start in late May and be completed around August, with the bridge reduced to one lane of alternating traffic.

Other structures scheduled for replacement this year include, in relative order, Little Hangman Creek on ID-60 near the Washington borer, Texas Creek on ID-11 near Weippe and Round Prairie Creek on US-95 near the Canadian border.

In 2020, ID-6 over Santa Creek near Michael Road, ID-3 over Cedar Creek near Clarkia and ID-57 over Kalispell Creek near Nordman will be reconstructed.

Each structure is expected to take two or three months with simultaneous work possible. In general, they will be reduced to one lane with alternating traffic controlled by flaggers or temporary signals.

All work is expected to be completed by spring 2021, with some work possible over the winter. T. La Riviere Equipment & Excavation, Inc. will replace the seven structures for $8.8 million.

Paving near Time Zone Bridge underway

Construction underway on US-95 near the Time Zone Bridge.

Work is ongoing to resurface 13 miles of US-95 north of the Time Zone Bridge. Construction began last week and is expected to wrap up in August.

The highway is reduced to one lane with alternating traffic controlled by flaggers. Drivers should expect up to 15-minute delays. Various pull outs on US-95 will be temporarily closed for a few hours at a time as the route is paved in the immediate area.

Contractors plan to work during weekdays, though some work at night and on the weekends may be necessary as construction continues.

During non-working hours and holidays, two lanes will be open. Learn more at itdprojects.org/us95goffto210.
