St. Croix Crossing project to begin bridge construction overnight work beginning June 9

Asphalt paving begins on Highway 36 and North Frontage Road within project limits

June 5, 2014

STILLWATER, Minn. – Construction crews will begin working during both day and overnight hours on the St. Croix Crossing bridge beginning the week of June 9 through fall 2014. Overnight hours are anticipated to be 5 p.m. to 3 a.m. Monday through Saturday. This is needed to meet schedule goals and complete river piers construction on time.

Noise impacts associated with the nighttime work will be very similar to the noise associated with ongoing daytime work. Crews do not anticipate hauling any materials with trucks during the overnight hours. For safety reasons, lights in the work area are required at all times. Nearby residents may experience some lighting impacts related to this work.

Pile driving for the pier locations on Minnesota land (Piers 1-7) is nearly complete. This week, construction crews built an additional land pier to its full height, bringing the total of completed piers to seven of 23. In addition, 22 of 23 land pier footings are now complete – crews recently completed three more of these footings. Two of the three bridge abutments are also complete. See progress map.

Additional pile driving for the bridge falsework will begin in late June. This pile driving should last for a few weeks, weather permitting. Falsework is a series of temporary structures that support the bridge spans during construction, until the bridge can support itself.

Pile driving also will occur on the Wisconsin side of the St. Croix River during the 2014 construction season to construct the pier on Wisconsin land.

Minnesota approach work

Construction crews have begun paving the westbound lanes of Highway 36 and portions of the North Frontage Road within the project limits. Driveway reconstruction to businesses adjacent to the North Frontage Road continues, as well as placing curb and gutter. Though these access points may shift, business access will be available at all times.

A traffic shift is anticipated to occur on Osgood Avenue north of Highway 36 on Tuesday, June 10, weather permitting. Motorists will move to the newly-constructed east side of the road while crews work on utilities and road reconstruction on the west side. Business access will be available at all times. All lanes on Osgood Avenue north of Highway 36 are anticipated to re-open at the end of June, weather permitting.

All other traffic impacts continue while crews reconstruct the road and install utilities:

  • Highway 36 traffic is single lane in each direction from Highway 95 to the Washington Avenue/Norell Avenue intersection.
  • Highway 95 traffic is single lane in each direction from Highway 36 to the north entrance to Sunnyside Marina.
  • Greeley Street north of Highway 36 and Osgood Avenue north of Highway 36 have shifted traffic lanes.
  • South Frontage Road is closed to through traffic east of Osgood Avenue 

Throughout 2014 construction, Highway 36 and Highway 95 in Minnesota will remain open. Access to businesses and residences will be available at all times.

WIS 35 overpass work

This week, the contractor again focused on the bridge abutment radius walls for the new WIS 35 overpass that will travel over the newly aligned WIS 64. Concrete was placed for more of the walls. Soil excavation also continued at the new interchange at County E.

Next week, crews anticipate pouring the bridge deck, complete placing concrete for the bridge abutment radius walls and backfilling the bridge abutments, in addition to other ongoing activities.

More detailed information and maps showing the 2014 construction schedule are available at www.mndot.gov/stcroixcrossing.

Minnesota approach work will be substantially complete by the end of 2014 and the new St. Croix Crossing bridge/Wisconsin approach work will be complete in late summer/early fall 2016. When all work 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.
