Date change: Lookout Trail 2-week closure to begin Oct. 21

Crews ask pedestrians to stay out of all project work zones

Motorists and area residents will experience a 2-week closure of Lookout Trail in Oak Park Heights beginning Monday, Oct. 21, weather permitting, as part of the St. Croix Crossing construction. Through traffic should follow the signed detour, and area residents will always be able to access their homes. Crews will complete utility work during this closure.

For the public’s safety and crew members’ safety, the St. Croix Crossing project team asks area pedestrians and bicyclists to keep out of the active construction areas and off of construction equipment. Crews have been encountering several onlookers from inside construction zones. Please respect closure signage, including barricades and fencing. The old Beach Road bridge and the closed ramp from Beach Road to westbound Highway 36 are inside the active construction zone. The project team appreciates the community’s interest in the work, but asks that the public remains in safe locations.

Planned openings, weather permitting

  • Single-lane traffic will move to newly constructed eastbound lanes of Highway 36 in late-October.
  • New ramp between Highway 36 and Highway 95 will open in late-October.
  • New Highway 95 will open in late-October.
  • New Beach Road bridge will open in late-November.

Bridge foundations work

Bridge foundations work in the St. Croix River is on track to be complete by early 2014. A major part of this is drilling 40 caissons into the muck and bedrock up to 120 feet below the river surface. Caissons are 9-feet diameter steel casings filled with rebar and concrete to create solid foundations for the new bridge. Completing all 40 of these will be a major project milestone.

Then, crews pour a concrete footing and a column at each pier location that will eventually attach to the bridge superstructure. The columns will be visible and stick up about 15 feet above the water’s surface. Track the progress of caisson construction on the project website, updated every Wednesday.

Project information

The Minnesota approach project will be complete by fall 2014. The new St. Croix Crossing bridge and Wisconsin approach project will be complete by fall 2016. When all work is finished, motorists will have smoother highway pavement surfaces, improved flow at intersections, an improved frontage road system in Oak Park Heights and a new river crossing between Minnesota and Wisconsin. All of this will occur while maintaining or restoring the area’s cultural, historic and environmental resources.

More information on continued impacts, detours and other updates is available on the project website.
