Maryland Route 450 will be closed for the replacement of four culverts between Parole and Crofton this weekend. A similar closure is scheduled next weekend. The goal is to reduce the frequency of street flooding near several streams.
WTOP reported on the planned closures several months ago. Read more here.
The highway is scheduled to be closed to through traffic between Route 424 and Crownsville Road until early Monday morning this weekend and next. Eastbound traffic will be turned around near Rutland Road. Westbound lanes will be blocked west of Crownsville Road.
Route 450, or Defense Highway, courses through a low-lying, marshy area between Crofton and Annapolis. A portion of the highway near the confluence of three South River tributaries is often submerged after periods of rain.
State officials say the flooding is getting worse and indicate that climate change may be playing a role.
