Construction begins on interim ramp and pedestrian tunnel construction at I-15 / U.S. 20 intersection

Idaho Falls

The following is a news release from the Idaho Transportation Department.

IDAHO FALLS – Construction has begun at the northbound I-15 off-ramp onto US-20 eastbound (exit 119) to build and add a free-flowing right turn lane onto eastbound US-20.

The Idaho Transportation Department will add the free-flowing right turn lane to allow for constant traffic movement which will in turn help alleviate the traffic backlog onto the interstate and highway.

ITD will also build and install a pedestrian tunnel and pathway under the roadway at this intersection, replacing the current at-grade crosswalk. By building this tunnel it will provide a much safer passage for bicyclists and pedestrians to cross the road.

Motorists should anticipate reduced speeds and off-ramp lanes reduced to a single-lane right-hand turn only at the intersection. Beginning Monday, April 12, the left turn lane at the exit 119 intersection turning westbound onto US-20/Grandview Drive will be temporarily closed throughout the duration of the project.

Traffic control will be in place with directional and detour signage. There will be a 12′ width restriction in place for exit 119. All US-20/Grandview Drive westbound traffic will need to take exit 118, following detour signage.

Drivers should expect 15 to 20 minute delays in the area and are encouraged to take a temporary alternate route in the interim. Motorists are encouraged to pay attention to the work zone signage, follow the appropriate detour signs and plan their commute accordingly.

This project is expected to be completed by July. ITD asks drivers to navigate safely and attentively through the work zones.
