Overview
ITD will also replace the signal and widen the 27th Street at the intersection to make room for future planned widening. The new signal will include flashing yellow arrows for permissive left turns rather than the green ball.
The department will also raise the grade at the intersection to make it level so that vehicles, particularly commercial trucks, do not bottom out when passing through. New curb and gutter will help with drainage.
Intersection changes
In winter 2025, the Idaho Transportation Department will replace the signal and the culvert over G Canal.
G Canal was built in the 1930s and runs underneath State Highway 27 at the intersection of 27th Street in Burley. The culvert was lengthened in the 1960s and 1980s, but now the structure is ready for replacement.

Anticipated Construction Impacts
Construction is expected to begin between mid-October 2025 and mid-March in 2026 when G Canal is dry and not being used for irrigation.
The intersection will close completely for up to two months to allow crews to dig up the existing culvert and replace it, as well as install the new signal. During this time some utility companies will also make changes to their infrastructure.
After excavation is complete, the intersection will reopen, but drivers should expect to travel on gravel surfaces until warmer temperatures allow for paving. The entire project is planned for completion in summer 2026.
Partnership with the city of Burley
ITD is working with city staff to design and build improvements to accommodate future widening of 27th Street. A short right turn lane will be added to 27th Street to head north on SH-27.
The city will also take advantage of ongoing construction to relocate a water line.
