July 24, 2025 Update

The northbound Minnesota Highway 100 on-ramp at West 50th Street is scheduled to close Monday, July 28, as the Vernon Avenue & Highway 100 Interchange project moves into Stage 3A of construction. The closure is expected to last until late fall.

Entering Stage 3 marks the start of the most disruptive portion of the project for residents and businesses, but it is also the phase where the most visible infrastructure improvements will take shape. Foundational work completed so far includes bridge demolition, underground utility installation, new bridge foundations and intersection reconstruction. Between July 28 and the project’s completion in November, drivers should expect varying closures of Highway 100 on- and off-ramps at Vernon and West 50th, along with longer detours, as crews complete bridge work, build new ramp tie-ins, install new traffic signals and construct a new noise wall along the northbound on-ramp to Highway 100.

Stage 3A of construction will be divided into two parts, lasting until late fall:

• Stage 3A - Part 1 (begins July 28)—the northbound Highway 100 on-ramp at West 50th closes. This closure allows for construction of a new 20-foot-high, approximately 1,000-foot-long noise wall along the northbound lanes to reduce traffic noise for nearby Sunnyslope neighborhood residents. All other project closures remain in place, including no thru traffic on Vernon within the construction zone and continued work at the Vernon and Interlachen Boulevard intersection.
• Stage 3A - Part 2 (future stage; expected to begin late summer)—the northbound Highway 100 on-ramp remains closed, and the southbound Highway 100 exit ramp to Vernon/West 50th also closes. All other project road closures remain in place.

While the closure is in place, drivers needing to go north on Highway 100 in this area should take southbound Highway 100 from Eden Avenue, then use eastbound Highway 62 to return to northbound Highway 100. Local tra­ffic may use frontage roads and the northbound on-ramp at Benton Avenue. The interactive detour map and image versions of the Stage 3A maps, along with much more info about the project, are available at this site.
