New I-64/Highway 40 interchanges delayed​

New Interstate 64/Highway 40 interchanges that include an exit at Tower Grove Avenue to access the Washington University Medical Center and a new ramp from Boyle Avenue onto westbound I-64/40 have been delayed.

The interchanges, which will give employees a new route to access the east side of the medical center, now are expected to open in mid-July.

The interchanges are part of a road- and bridge-construction project to improve the flow of traffic around Kingshighway and the east side of the Medical Campus. The project is a partnership between Washington University School of Medicine, BJC HealthCare and the Missouri Department of Transportation.
