Project Name:

TSIP-IA 92/A Avenue corridor and US 63/Market Street corridor 3-Lane Conversion and C Avenue Traffic Signal Installation Project

Project Locations:

IA 92/ A Avenue from Highway 432 to the east corporate limits, and on Highway 63/Market Street from 350 feet south of 16th Avenue to 2nd Avenue. Intersection of Highway 63/Market Street and C Avenue.


Project Description:

  • The scope of work on this project includes the conversion from the existing 2 or 4-lane roads to 3-lane roads on Highway 92/A Avenue and Highway 63/Market Street.  The majority of work on this project involves pavement markings along with adjustments to signal heads.  This project also includes a new traffic signal at Highway 63/Market Street and C Avenue.  This project is divided into 3 divisions: Division 1 includes all work associated with pavement reconstruction and includes $500,000 in funding from the IDOT TSIP (Traffic Safety Improvement Program), Division 2 includes C Avenue traffic signalization and includes $139,000 in funding from the IDOT TSIP, and Division 3 includes traffic signal installation with the city solely responsible for these costs.  

Project Benefits:

  • These improvements are a part of improvements based on a study thru the Iowa Department of Transportation with the Traffic Safety Improvement Program.  The 3-lane conversion will improve safety and efficiency on these corridors, minimize traffic delays and congestion, and allow for future planning.
