Signal work is expected to begin next week at the intersection of Blue Lakes Boulevard (U.S. Highway 93) and Fillmore Street/Bridgeview Boulevard. This is part of a larger pavement rehabilitation project scheduled to occur this summer on Blue Lakes Boulevard from the Perrine Bridge to Pole Line Road.

In the coming weeks, crews will complete preliminary foundation work on the traffic signal. A total signal replacement will occur at the intersection after the paving on US-93 is finished later this summer.

“Being able to start the initial foundation work now will help expedite the construction timeline and further reduce impacts to motorists traveling through this busy corridor this summer,” said ITD Project Manager Steve Hunter.

No lane adjustments or changes to current traffic patterns will occur with the signal replacement.

“We are not altering how motorists travel through the intersection, just replacing the traffic signal, foundation, and associated components,” stated Hunter.

Motorists are encouraged to watch for lane reductions and crews in the area. Most signal work will occur during daytime hours.

In conjunction with the signal replacement, ITD will improve the pavement on Blue Lakes Boulevard starting in June. More details about construction will be shared at an upcoming public meeting.

As part of Governor Brad Little’s “Leading Idaho” initiative, the 2021 Idaho Legislature dedicated $126 million of one-time funds from Idaho’s budget surplus to transportation projects statewide. The funds were split 60/40 between ITD and local jurisdictions. Construction on the Blue Lakes project is paid for with ITD’s portion of the funds that will accelerate projects to replace bridges, restore pavements, and improve mobility in communities across Idaho.
