ID-21: One park-n-ski access open, route to Stanley remains closed

LOWMAN – Idaho Transporation Department crews have cleared a section of Idaho Highway 21 from Idaho City to Mores Creek following significant snowfall. The section of ID-21 from Lowman to Stanley known as Canyon Creek remains closed.

A large avalanche hit ID-21 in 2017

In the last week, the area has received more than 5 feet of snow. Avalanche danger has prevented crews from working to clear the Canyon Creek section. Slides have hit the road and piled more than 50 feet of snow on top of the roadway. Additional crews are dispatched to assist efforts to clear these historic slides.

The segment between Idaho City and Lowman is a popular destination for winter recreationists, including park-n-ski locations accessing state-owned yurts. Crews have been blowing snow off the road moving south to north. Currently, the road is clear to Mores Creek park-n-ski. Access to the following park-n-ski locations remains closed (map).

  • Whoop Um Up
  • Gold Fork
  • Banner Ridge
  • Beaver Creek Summit

Crews will continue to work over the weekend to clear snow from the road. For updates, check 511 at 511.idaho.gov.

TRAVEL ADVISORY: Motorists urged to use caution on ID-55 between Banks and Cascade

BOISE – The Idaho Transportation Department is warning motorists to use caution on Idaho Highway 55 between Banks and Cascade due to rapidly deteriorating pavement.

Harsh winter weather has caused the pavement in this stretch to break up, leaving significant potholes and frost heaves. ITD maintenance crews have been working non-stop to fill potholes with a cold patch material, but inclement weather is causing new potholes to rapidly form and some patches to fail.

“Crews are out plowing snow and patching potholes around the clock,” said ITD Southwest District Maintenance Manager Michael Garz. “But it’s not doing the trick. Rain, snow, and temperature swings are popping out patches, leaving the road in rough shape.”

ITD has placed several warning signs on the road, urging drivers to use caution and reduce their speed. More signs are currently being deployed. Using alternate routes, such as U.S. 95 is strongly encouraged.

The Department has a project funded to repave this stretch of road this year. That work will begin as soon as weather allows this spring. For more information on the project, visit https://itdprojects.org/id55smithsferryrepave/

Innovative virtual public meeting allows Idahoans to comment on upcoming ID-55 project online

Smiths Ferry Featured

To maximize the public’s ability to provide input on upcoming construction, the Idaho Transportation Department is launching a virtual public meeting on proposed improvements for Idaho Highway 55 from Smiths Ferry to Round Valley.

You can view the project information and participate in the virtual public meeting by clicking here or visiting https://bit.ly/2BCNCzx.The Department will receive public comments until March 3. The online meeting tool allows visitors to interactively learn about the project and provide direct feedback to ITD.

The improvements will address existing safety concerns on the corridor by widening the road, adding ditches to catch rockfall and constructing shoulders and guardrail where appropriate. Additional work will improve wildlife habitat and passage under the roadway. The result will be a safer corridor with higher speed limits to improve mobility.

“This project will affect a diverse group of people from far and wide, including nearby residents and recreationists from around the region,” said ITD engineering manager Jason Brinkman. “This virtual public meeting allows us to effectively reach those groups and get their input to help us make well-informed decisions.”

Construction could begin as soon as the Fall of 2019. The work will require significant blasting and excavating of the hillsides adjacent to ID-55. To complete this work, regular closures of several hours will be enforced. ITD will conduct extensive public outreach to inform users of the highway about these impacts and work with them to mitigate the impacts of construction.

Construction of ID-55 improvements in Marsing begins; open house Jan. 24

ID-55 Marsing Improvements

Construction of improvements to Idaho Highway 55 through downtown Marsing has begun. The project will rebuild the Snake River Bridge and repave the highway from the river to the U.S. 95 Junction. When complete, the project will enhance local business opportunities and improve safety and mobility through the area.

Initial work on irrigation lines began Monday, January 14. Major work includes replacing the School Drain pipe and C-Line Canal pipe. Traffic will be reduced to one lane and a temporary signal will direct alternating traffic. Work will be limited to daytime hours, though the lane closure and signal will operate 24/7 for the next 3-4 weeks.

ITD invites the public to an open house to review the final construction plans for this project. The open house will be held Thursday, Jan. 24 from 4 to 7 p.m. at the American Legion Hall in Marsing (126 2nd Ave. W). Attendees will have an opportunity to view construction plans for the new Snake River Bridge and ID-55 improvements, ask questions  of project staff, and learn how to stay informed during construction.

“We are encouraging motorists to plan extra time when driving through the areas during construction,” said David Barrett, ITD Project Manager. “We are improving a major route used to haul agricultural products and move people to and through a beautiful part of Southeast Idaho.”

Work to rebuild the bridge will begin in earnest this spring. During construction, one lane of the bridge will be open to traffic with a 14-foot width restriction. The new bridge is expected to be complete by the summer of 2020.

The contractor for this $20.9 million project is Wadsworth Brothers Construction out of Salt Lake City, Utah.

Overnight detours in Nampa’s Karcher Interchange for sign placement week of Oct. 22

BOISE— Segments of the Interstate 84 Karcher Interchange in Nampa will be closed overnight Oct. 23 and 24 as crews install new overhead signs.

Detours will be in place during construction.

  • On Tues., Oct. 23, the Midland Blvd. bridge over I-84 will be closed at 8 p.m. and will reopen to traffic Wed., Oct. 24 at 5 a.m. Crews will be installing a new overhead sign structure. Pedestrians will need to use an alternative route while the structure is installed.
  • On Wed., Oct. 24, the Exit 33 loop ramp and on-ramp to I-84 will be closed at 8 p.m. and will reopen to traffic the next morning at 5 a.m. Crews will be installing a new overhead sign structure.

Reconstruction of the interchange will be complete in early November and is designed to improve traffic flow and safety in this highly traveled area. Project improvements include:

*Adding a second southbound lane to Midland Blvd.
*Adding a second left turn lane from the Karcher Bypass to southbound Midland Blvd.
*Upgrading sidewalks and traffic signals
*Permanently removing the westbound off-ramp (Exit 33B)

The I-84 corridor in Nampa is a very active construction zone with multiple projects occurring in the same vicinity. ITD encourages drivers to slow down, pay attention, and give construction crews space to safely work.

The Exit 33B westbound ramp on the Interstate 84 Karcher Interchange in Nampa will be permanently removed Monday, Oct. 15. Crews will remove the ramp beginning at 8 p.m. Monday and work will be complete by 5 a.m. Tuesday.

Moving forward, all westbound traffic will use the loop ramp, which will be referred to as Exit 33. Signs in the area will reflect the change.

Reconstruction of the interchange is on schedule to be complete by the first week of November. Project improvements include:

*Adding a second southbound lane to Midland Blvd.
*Adding a second left turn lane from the Karcher Bypass to southbound Midland Blvd.
*Upgrading sidewalks and traffic signals.

The project is jointly funded by the city of Nampa and ITD. Central Paving is the contractor.

 

Interstate 84 expansion project in Nampa begins Sept. 26

The outside shoulders of I-84 will receive temporary widening to accommodate traffic during future construction.

The Idaho Transportation Department will begin reconstructing and widening the shoulders of I-84 between the Karcher and Franklin Boulevard interchanges on Wednesday, Sept. 26. This is the first step of widening I-84 through Nampa.

All traffic lanes will remain open between 5 a.m. and 10 p.m. as crews will work primarily at night.  Speeds will be reduced to 55 mph during the day and night. Traffic will be down to one lane in each direction during construction times. The work will continue until mid-November.

The newly reconstructed shoulders will be used to keep two lanes of traffic flowing in each direction when I-84 is widened to three lanes between Karcher Road and Franklin Boulevard starting next spring.

In 2019 and 2020, ITD will replace the Karcher Overpass, redesign and reconstruct the Northside Interchange, and rebuild the bridges over the railroad and Mason Creek. Improvements are expected to improve safety, capacity and traffic flow in Canyon County for many years.

A separate environmental study is underway to identify needed improvements between the city of Caldwell and the Karcher Interchange.
