COLLEGEVILLE -- An overpass above I-94 which serves motorists heading to and from St. John's University will be closed to traffic most of next week.

The University of Minnesota is installing equipment on the Stearns County Road 159/135th Avenue bridge as part of a study on bridge performance. The work will prompt single-lane traffic on Monday and will close the bridge for 8-out-of-every-10 minutes Tuesday through Thursday.

Flaggers will direct traffic through the work zone during those "open" times.

A detour will also direct traffic to County Road 9 in Avon and back eastbound on I-94 to the exit.

All exit ramps will remain open during the construction.
