Drivers on State Highway 3 should plan for lane restrictions and delays starting today as crews begin replacing a nearly century-old bridge just north of the State Highway 6 Junction.
During construction:
- Traffic will be reduced to one lane.
- A temporary signal will control alternating traffic flow.
- A shoofly detour (a temporary bypass road) will guide vehicles around the work zone.
The bridge, originally built in 1934, is being replaced due to age and ongoing maintenance needs. The $2 million project will improve both safety and functionality along this stretch of SH-3:
- The new bridge will support heavier loads and increased traffic volumes.
- The road will be widened to include 5-foot shoulders for enhanced safety.
- Updated guardrail will be installed along the improved section.
“These updates are vital for ensuring the long-term safety and reliability of the route, especially for the freight and logging industries that rely on it every day,” said Project Manager Jacob Edlund.
This project is expected to be complete by late fall of this year.
Delays and lane restrictions are expected to last throughout the summer. Drivers are encouraged to check Idaho 511 for the latest updates on road conditions and travel impacts.
