Crews working on the new St. Croix River bridge can continue to use an industrial strength epoxy to seal together massive precast bridge-deck concrete segments until temperatures drop to 28 degrees, reports Twin Cities.com.

The epoxy, called Sitka, will not set properly at 28 degrees or lower. The epoxy is being used on 650 bridge-deck segments, which each weigh 170 tons. The bridge is about 60 percent complete and is estimated to cost between $580 million and $646 million.

The segments are being joined with high-strength, post-tensioned steel strands -- 1,969 miles in total -- inside the bridge, according to Twin Cities.com.
