About the projectProject limits
The reconstruction project includes 6.68 miles of northbound Interstate 380 from the U.S. 20 interchange to west of River Forest Road in Evansdale. (Note: While I-380 runs east and west at this location, the entire route runs north and south, so the road designation remains a north- and southbound.)
The scope of the project includes replacing the current pavement with 11.5-inch thick concrete and widening the current roadway 2 feet, creating a 14-foot driving lane and 12-foot passing lane. The inside and outside shoulders will be reconstructed and all bridge approaches and guardrails will be replaced. Safety will be enhanced by replacing the pier protection in the medians with high-tension cable guardrail.
The northbound interchange ramps at River Forest Road and Black Hawk County Road V-49 (Raymond Road) will close during reconstruction. Median crossovers will be used to move northbound traffic to the southbound lanes.The Evansdale Drive interchange ramps will remain open for both northbound and southbound I-380 traffic during the reconstruction project.
There will be two hard surface emergency parking areas in southbound lanes that will be used if a vehicle becomes disabled while in the construction area, allowing traffic to continue to flow.
The project will include cameras and sensors so people can monitor any congestion/crash problems at 511ia.org.
