Conowingo work to temporarily close U.S. 1

Hydro dam gates to be removed for upkeep

Traffic on U.S. 1 will be stopped for up to 45 minutes on Tuesday and Wednesday to allow workers at the Conowingo Hydroelectric Generating Station to remove dam gates for maintenance.

The highway will be closed in both directions between Maryland Route 222 and Shures Landing Road at some point between 9 a.m. and 3 p.m., according to Exelon Generation, which operates the dam. Crews will remove and haul two crest gates from the dam to the upper parking lot at the Conowingo Visitor Center.

Exelon expects to fix six of 50 crest gates over the next few years. As the project progresses, additional closures to U.S. 1 may be necessary, the company said.
