Park Police officers closed the Baltimore Washington Parkway in both directions at Greenbelt Road just after noon on Friday, August 24th, due to concrete portions of the Greenbelt Road Bridge falling onto the northbound lanes of the parkway. There were no accidents and no one was injured by the concrete. Both north and southbound lanes were shut down initially as a safety precaution. It was soon determined the damage was limited to the northbound lanes, however, and at approximately 1 p.m. the southbound lanes were reopened. The NPS worked with Federal Highway Administration (FHWA) inspectors to evaluate the extent of the damage. They determined that the damage was cosmetic and that there were no structural issues. NPS employees removed the remaining loose concrete and the parkway was cleaned and cleared for vehicular travel. The entire parkway was reopened by 3:45 p.m. for the evening home commute. On Monday, August 27th, NPS and FHWA officials conducted further inspections of the Greenbelt Road Bridge. One northbound lane of the parkway was partially closed for about four hours during the inspection. On the following day, a southbound lane was partially closed, again for about four hours, so that the rest of the bridge could be evaluated. An analysis of the inspection results will be conducted to determine what short- and/or long-term repairs may be needed. There was extensive media coverage of this incident in light of the recent bridge collapse in Minneapolis.
