St. Croix Crossing project resumes bridge deck construction
Barge traffic on the St. Croix and Mississippi rivers to increase in 2016
March 31, 2016
STILLWATER, Minn. – Construction crews resumed placing pre-cast concrete segments that make up the bridge deck for the new river crossing and the Minnesota approach on March 28.
Specifically, crews continued river bridge deck construction at Piers 8 and 9 and began this same construction at Pier 11. By mid-April, they will be placing segments at all five river piers.
As of fall 2015, crews competed the following river bridge deck construction:
- 59 percent of segments were installed at Pier 8, closest to the Minn. shoreline
- 55 percent of segments were installed at Pier 9
- 7 percent of segments were installed at Pier 12, closest to the Wisc. bluff
The first pre-cast segment was lifted at Pier 11, closer to the Wisconsin shoreline, on March 28. The first eastbound and westbound segments at both Piers 10 and 11 will be placed using a construction method that involves connecting threaded rods to a single segment and lifting it into place from the barge deck using hydraulic jacks.
The contractor also resumed pre-cast segment placement for the Minnesota approach.
- Crews are placing segments at Pier 3 for the westbound Highway 36 approach bridge. Crews completed construction of the Highway 36 approach bridges from the west abutment to Pier 2 in 2015.
- Crews are again placing segments at Pier 2 for the off-ramp to Hwy 95. In 2015, 36 percent of segments were installed at this pier location.
Boaters will see an increase in barge traffic on both the St. Croix and Mississippi rivers in 2016. The St. Croix Crossing project is using five barges to transport pre-cast concrete segments that make up the river bridge deck from its Grey Cloud Island casting yard near Cottage Grove to the bridge construction site north of Bayport, Minn. These barges will make frequent trips between destinations, often daily. See more information (JPG).
