PROJECT DESCRIPTIONMar 2015 roundabout rendering

Street reconstruction and installation of a roundabout at the intersection of 7th Avenue and 7th Street.

This will implement a long term traffic management plan for Marion’s core, balancing traffic between  6th and 7th Avenues and creating a more pedestrian-friendly atmosphere in Uptown Marion. The Central Corridor Master Plan was adopted by City Council in 2009.

Physical improvements include new street, roundabout, sidewalk, trail and utilities as well as new street lights and signage.

The project is expected to cost approximately $2.9 million. This does not include property acquisitions or building demolition.It is funded through general obligation bonds and a $1 million grant from the Iowa Department of Transportation’s Iowa Clean Air Attainment Program. Individual property owners will not be assessed.
