The following information was found on the BJC Campus Renewal Project website:
A project to create a traditional intersection at Forest Park Parkway and Kingshighway will begin December 5 (and is projected to be completed July 2017).
The current configuration, with Forest Park Parkway running under Kingshighway, presents challenges for drivers accessing the medical center, the Central West End and Forest Park. Eastbound Forest Park Parkway drivers cannot turn onto northbound Kingshighway. Drivers on Kingshighway cannot access westbound Forest Park Parkway from either direction.
Information found below details the benefits, impact and timeline of the project.
