TRAFFIC UPDATE: Interim ramp and pedestrian tunnel construction has begun at the I-15/US-20 intersection (exit 119)

UPDATE - ITD will be temporarily closing the east bound Grandview Dr. right-lane onto US-20. This temporary lane closure will be closed starting tonight at 9pm, June 15 thru Sunday, June 20.

During this temporary lane closure work will entail relocating and assembling the traffic signal, paving, pouring and curing concrete. Pedestrian access will be established during this next phase as crews will have a walking path open to the public.

Motorists are encouraged to pay attention to the work zone signage, follow the appropriate detour signs and plan their commute accordingly.

Original Release

*The previous release included incorrect information about the additional right lane. This project is adding an additional right turn lane, however will NOT be a free flowing right turn lane. The additional lane will stop at signal as it currently exists. That signal will also just being updated and replaced.

Adding the second right turn lane will allow for a more efficient traffic flow turning right onto US-20. ITD will continue to watch the traffic at this ramp and make additional adjustments as needed.

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 (ITD) 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 cross walk. 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 - 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.
