COMPLETE: SH-39 Blackfoot: Widening and Intersection Improvements

SH-39 from approximately Thomas Road to Collins Siding Road was widened with a continuous center turn lane to provide safety improvements for increasing traffic volumes in the corridor.

The intersection of SH 39 and Collins Siding Road was signalized. The intersection is also seeing increased traffic volumes, requiring improvements for both safety and capacity. Traffic studies and concept designs were presented to the public in early 2021 and a signalized intersection was selected as the preferred alternative by both the traffic study and public.
