Hurricane Sandy's pending arrival forced the State Highway Administration to postpone this weekend's attempt to replace one of two spans over the Baltimore-Washington Parkway at West Nursery Road.
The $6 million project calls for swapping out two 60-year-old bridges that carry traffic to Baltimore-Washington International Thurgood Marshall Airport and its business district with two new spans that were built in the highway median. A massive multiwheel transporter has been assembled for the heavy lifting.
"The predictions of when the storm will hit are still a little iffy, and bands of rain and wind might arrive sooner. If we were forced to stop because of conditions, we didn't want to have a big hole and the new bridge not in place," said Valerie Burnette Edgar, SHA spokeswoman.
Last weekend, the project came to a halt when the unbolted northbound bridge deck shifted as it was lifted from the abutments. Four cranes were brought to the construction site to hoist the old bridge back into place.
