Improvements start late May on SH-33 near Victor

Simple map of where a passing and center turn lane will be constructed on SH-33.

Starting in late May the Idaho Transportation Department will widen State Highway 33 near Victor to include a passing lane, center turn lane, and right turn lanes. Construction is anticipated to start on May 20.

Motorists can plan on one lane remaining open throughout construction, which is expected to last until early to mid-September. Fifteen-minute wait times between milepost 151 and 153 may occur as flaggers direct traffic. Cones will be moved out of the way of traffic each night, and all lanes will be open.

A new passing lane for eastbound traffic between milepost 151 and 152 will improve the flow of traffic on SH-33 before motorists begin to traverse Teton Pass. A center turn lane will continue after the passing lane to make it easier for drivers to access area subdivisions and Trail Creek Community Pond. Baseline Road will also be realigned to improve visibility at the intersection of SH-33.

Old cattle underpasses that are no longer used exist in three different areas along SH-33 where this work will be done. This means crews need to remove old cement structures, excavate the ground down eight feet and then rebuild one foot at a time to ensure road integrity. Motorists will note additional time spent on those sections of work, with crews present in those areas for longer and flaggers remaining overnight.

This project is made possible through a grant obtained by Teton County of Wyoming in partnership with ITD, Teton County of Idaho, the town of Jackson, the city of Driggs and others. Information about additional planned improvements through the grant can be found at
