Osgood Ramp

I-15 Osgood Exit Ramp Construction MapI-15 Osgood Exit Ramp Project

The Idaho Transportation Department will reconstruct three of the ramps at the I-15, Osgood Interchange (Exit 128). The Osgood Interchange is located north of Idaho Falls.

Project details

Traffic impacts:
• Occasional lane restrictions on I-15. Shoulders will be restricted.
• The speed limit on I-15 will be reduced to 65 mph.
• The northbound on-ramp will be closed until Mid-October. Traffic will be detoured to the I-15 interchange in Roberts, Idaho, via Bassett Road (Old Highway 91).

The existing ramps were designed in 1958 and need to be improved. New, longer ramps will give vehicles more room to accelerate and decelerate when entering and exiting I-15.

The project includes:
• Replacing the northbound on-ramp and both southbound ramps.
• Realigning the ramps to improve sight distance.
• Upgrading guardrail.

Along this project route the interstate road surface is deteriorating and needs to be replaced. The resurfacing work will eliminate rough sections and soft spots in the road. As a part of this project, ITD will also upgrade the guardrail on I-15. Through a method called Cold-in-Place Recycling, ITD will re-use the old pavement in the new roadway. This method reduces waste and lowers costs.
