St. Croix Crossing Minnesota Loop Trail construction underway
Aug. 26, 2015
River crossing stay cable installation to begin
STILLWATER, Minn. – Minnesota Loop Trail construction as part of the St. Croix Crossing project is underway. This week, the contractor, Veit, is securing a historic wall along the future trail and removing some trees and other vegetation.
Loop Trail construction will take place in phases from 2015 to 2017. This year’s construction will focus on the stretch of trail from north of Sunnyside Marina to north of Nelson Street in downtown Stillwater. Trail sections will be open for use after they are constructed.
The 4.7-mile trail will accommodate bicycle and pedestrian traffic and use a designated lane on the new St. Croix Crossing and the existing Stillwater Lift Bridge, which will be converted to a bicycle/pedestrian bridge once the new bridge is open to traffic. The Loop Trail will also connect to existing local and regional trails in Minnesota and Wisconsin. Learn more.
In addition, St. Croix Crossing bridge construction is approaching another important milestone. As early as Saturday, Aug. 29, construction crews will begin installing the pipe for the first stay cable at Pier 9.
An individual stay cable above the bridge’s driving surface will consist of 76 strands bunched together. Crews will string each strand by hand through a high density polyethylene pipe that anchors to the pier tower on one end and a stay segment on the opposite end. Once the strands are installed, crews stress the cable from inside the bridge using a hydraulic jack.
Crews will install stay cables and continue to place pre-cast river bridge segments at Piers 8 and 9—closest to the Minnesota shoreline—through the fall.
Other St. Croix Crossing bridge construction highlights
- Crews are placing reinforcement bar, or rebar, for the third of three sections of the Pier 10 crossbeam. The crossbeam connects the upstream and downstream pier columns at each pier location. Pier 10 crossbeam construction will be complete in September.
- Crews are placing rebar for the second of three sections of the Pier 11 crossbeam.
- Crews are constructing the overlook, or viewing deck, on the upstream side of Pier 12, closest to the Wisconsin shoreline. They will begin removing the truss and other falsework that supported crossbeam construction at this pier location after Labor Day.
- Crews will complete Pier 13 foundation excavation on the Wisconsin bluff this week.
- Crews started placing pre-cast approach segments at Pier 2E, east of Highway 95, on Aug. 25.
- Crews are removing the falsework under the eastbound Highway 36 approach span over Highway 95. Highway 95 at the Highway 36/95 interchange is anticipated to return to a two-lane traffic configuration in September.
- Crews are installing falsework and placing decking for the cast-in-place section of the eastbound Highway 36 Minnesota approach bridge.
Weigh-in-motion construction update
Weigh-in-motion construction is anticipated to be complete this week. The system that weighs commercial vehicles on Highway 36 is fully operational. There is minimal work remaining on the Highway 36 westbound ramp from Highway 5. Construction crews widened the ramp to provide law enforcement with a safe place to properly weigh commercial vehicles that trigger the weigh-in-motion loops on Highway 36.
Minnesota welcome sign construction update
Minnesota monument construction is anticipated to be complete the week of Aug. 31. Remaining work includes painting the retaining walls and landscaping.
Wisconsin approach work highlights
Recently completed work includes:
- Excavating the old County Road E and grading the new County Road E alignment.
- Finishing the slopes and ditches with fertilizer, seed, mulch and other erosion control items.
- Placing rock and gravel on the new westbound WIS 64 lanes.
Looking ahead, the contractor will:
- Continue to place rock and gravel.
- Install signs on the new County Road E alignment.
- Pave the new WIS 64 lanes on the north end of the project.
The new St. Croix Crossing bridge will open to traffic in fall 2016. When the St. Croix Crossing project is finished, motorists will have smoother highway pavement surfaces, improved flow at intersections, an improved frontage road system—including safer access—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.
