US-95: ID-53 Interchange & Garwood Overpass

This project is part of a larger vision to improve traffic flow and safety along US-95 between Garwood and Sagle.

ITD is in the process of reconfiguring several roadways near the current US-95 junctions with ID-53 and Garwood Road north of Hayden.

Construction details

Construction will last until fall 2021, with the new bridge and ID-53 interchange finished first in fall 2020. Work is now focused on building a new overpass at Garwood Road.

Project history

Some improvements to this area were first identified during the development of an environmental document to plan for the future traffic needs of the region, which were approved in 2010 after multiple open houses.

In 2017, an interim design was developed to realign and widen ID-53 between Ramsey Road and US-95. This design also included the replacement of the bridge over the railroad, the addition of a center turn lane and the extension of bike facilities from Ramsey Road to the trail east of US-95. Additional funding was secured through the GARVEE Program shortly after to design and construct this project.

Shared-use path

In keeping with the corridor design established during the development of the 2010 environmental document from Garwood to Sagle, in summer 2019 the current multi-use path along the east of US-95 was extended as part of a separate project.

The path now covers from just north of Garwood to Idaho Highway 54, where it connects with a trail to Farragut State Park.

Season 1 ends

Foundational structures for the new interchange and railroad bridge were completed, bringing the first season of construction to an end. Work will resume in the spring, but the detour will remain in place through the winter months.

October 2019

Extended NB detour

An extended detour for northbound traffic was put in place to ease traffic flow, with eastbound traffic on ID-53 being directed to the Chilco interchange rather than Garwood Road to access northbound US-95. Previously drivers were directed to access northbound US-95 via Garwood Road and Old US-95, which caused congestion due to the proximity of the US-95 and Garwood Road intersection.

August 2019

Detour in place

The signal at US-95 and ID-53 will be removed, and a detour will be in place to Garwood.

mid-July 2019

Construction begins

Construction began in mid-July, with work starting on ID-53.


After a short break, work will begin again this January. This will be the last season of work, with construction of the overpass at Garwood Road as the focus. View the updated construction overview for the second season.
