Full road closures on ID-55 Smiths Ferry project begin March 15

Spring construction picks back up on Idaho Highway 55 between Smiths Ferry and the Rainbow Bridge Monday, March 15. The Idaho Transportation Department’s project will widen shoulders, add guardrail, and straighten this curvy one-mile stretch of highway to improve safety. Watch the video below to see the project.

Earlier this month, crews removed snow and set up construction equipment in the canyon. Starting March 15, travelers should plan for full road closures Monday through Thursday from 10 a.m. to 2 p.m., due to controlled rock blasting needed to widen the road. When ID-55 is not closed, there will be one-way alternating traffic with 15-minute delays. This work schedule is expected through May, when crews will transition into summer operations.

ID-55 project between Smiths Ferry and Round Valley to start September 8

ID-55 at Smiths Ferry

The Idaho Transportation Department (ITD) starts road work on the Idaho Highway 55 safety-enhancement project between Smiths Ferry and Round Valley on September 8.

The public is invited to attend a virtual public meeting on Wednesday, September 2, from 6 p.m. – 7 p.m. where ITD representatives will give an overview of the project and take questions. The link to attend will be posted on the project website, itdprojects.org/ID55smithsferry, 15 minutes prior to the meeting.

Work will largely be done in fall, spring and summer months, with construction stopping during the winter. This fall, travelers can expect full closures on the roadway Monday through Thursday from 10 a.m. – 2 p.m. to allow for blasting and rock removal.

Motorists can find additional details on road closures and traffic patterns on the project website, and can sign up for email and text updates.

“Our goal with this project is to enhance the safety of this mile-long section of the roadway,” Project Manager Alex Deduck said. “Construction crews will remove about 146,000 tons of rock from the hillside, which we want to do very carefully to not create rockslides or impact the river.”

Crews will work on widening shoulders and straightening the curves of the road. This project will also provide a smoother, safer ride for motorists by adding guardrail.

Motorists should anticipate reduced speeds and lanes reduced to one-way alternating traffic during construction. Seasonal closures and traffic patterns will be as follows:

  • Fall (September – November): One-way alternating traffic controlled by a temporary signal; daytime and nighttime work, seven days a week; full road closures Monday – Thursday from 10 a.m. – 2 p.m.
  • Winter (December – Mid-March): No construction expected; all lanes open
  • Spring (Mid-March – Mid-May): One-way alternating traffic controlled by a temporary signal; daytime and nighttime work, seven days a week; full road closures Monday – Thursday from 10 a.m. – 2 p.m.
  • Summer (Mid-May – August): One-way alternating traffic controlled by flaggers; daytime and nighttime work, Monday – Friday

The project is expected to be completed by late fall 2022. ITD and the Idaho State Police advise motorists to slow down and pay attention when driving in work zones, where increased speeding fines and other penalties apply. Motorists are encouraged to plan ahead and dial 5-­1-­1 or visit 511.idaho.gov for information on the state highway or interstate system.
