SDOT road crews will continue maintenance work on the aging Magnolia Bridge next week.

Several expansion joints in the westbound travel lanes were repaired in late August and mid-September, and now crews are focusing on the east side of the bridge.

Eastbound traffic will be shifted to one of the bridge’s westbound lanes while repair work is being conducted 9 a.m. to 2:30 p.m. Monday to Wednesday, Sept. 24-26, and again on Friday, Sept. 28.

SDOT is still modeling traffic for a potential in-kind replacement — a new bridge that matches the design of the current one. A 30-percent replacement design from 2006 is being updated, the transportation department acknowledging the bridge will need replacing eventually. The in-kind replacement is estimated to cost $340-$420 million.

There are also several other alternatives being considered, which would cost between $170 million to $350 million.
