'Diverging Diamond' Groundbreaking Near Cox South

A groundbreaking to kick off a project to rebuild the National Avenue and James River Freeway (U.S. 60) interchange and make it safer to reach CoxHealth facilities nearby is scheduled for 2:30 p.m. Tuesday, Sept. 22, at Cox South Hospital.

The public is invited to attend the groundbreaking. The location is off Westview Street, west of National Avenue just south of the Cox South Hospital emergency entrance. (Download a parking map.)

The Missouri Department of Transportation, the City of Springfield and CoxHealth are partners in the construction of the city’s second “Diverging Diamond Interchange,” designed to improve north-south traffic flow and make it easier and safer for drivers to make left turns onto the freeway. The project also includes traffic flow improvements on the CoxHealth campus.

The $7.5 million project involves widening the National Avenue bridge over the James River Freeway, building auxiliary lanes on the freeway between National and Campbell avenues, widening the ramps at the interchange to provide dual northbound turn lanes and widening National Avenue between Bradford Parkway on the north and Kingsley Street on the south. A new access road and underpass underneath National Avenue will be built to connect CoxHealth facilities on either side of National Avenue.

The public-private partnership project is being funded by MoDOT American Recovery and Reinvestment Act funds, the City of Springfield’s voter-approved 1/8-cent sales tax for transportation and CoxHealth.

Completion is scheduled for August 2010.

During construction, access will be maintained at all times to the Cox South emergency department and all hospital facilities, as well as to area businesses and offices. Drivers are encouraged to use alternate routes when possible to avoid expected traffic slowdowns at the interchange, but anyone who must reach the hospital or other nearby businesses or medical facilities will be able to get there.

Current information about the construction and traffic will be available on Web sites maintained by MoDOT and the City of Springfield at  and Updates also will be available through Twitter ( and and via text message, e-mail or the Web with
