The Idaho Transportation Department will close 10th Avenue in Caldwell underneath the interchange bridge this Saturday, from 6 a.m. to 6 p.m. The closure is necessary for crews to install concrete girders that will support the new bridge deck.
The seven girders to be placed are made in Caldwell. Each girder is 140 feet long and weighs 133,000 pounds. Motorists will be detoured on Centennial Way during the closure, and shuttle buses will be available to transport pedestrians and bicyclists. Interstate 84 will not be impacted during this girder placement.
“Placing these girders is a major milestone in the project,” ITD Resident Engineer Styles Salek said. “The new bridge will accommodate the additional lanes being added to I-84, improving traffic flow and capacity in the area.”
This girder placement is part of the ongoing project on I-84 between the Centennial Way and Franklin Road interchanges in Caldwell. This comprehensive project, which began in November 2023, includes:
- Widening I-84 to three lanes in each direction, with auxiliary lanes between interchanges.
- Replacing the 10th Avenue Interchange.
- Removing one westbound on-ramp at the 10th Avenue Interchange.
- Updating the pedestrian overpass.
- Building a sound wall along Hannibal Street.
- Adding a traffic signal at the westbound ramps at the Centennial Way Interchange.
Drivers are reminded that the speed limit in the I-84 work zone is 55 mph. With workers, trucks, and heavy equipment operating close to traffic, ITD urges motorists to slow down, stay alert, and follow all posted signs.
