Scheduled water quality improvements along the Route 50/Route 301 corridor may cause some off-peak lane closures in the Edgewater and Davidsonville area, beginning in mid-January and extending until mid-March, according to a release issued by the Maryland State Highway Association.

"...the Maryland State Highway Administration (SHA) will construct stormwater bio-swales along the US 50/301 median from the Patuxent River at the Prince George’s County line to the South River near Annapolis," states the release. 

SHA says drivers should expect some shoulder and left lane closures as the work takes place. Nearly 88,000 cars travel this part of Route 50, according to SHA. The improvements should take about six weeks, weather permitting. 

Bio-swales are trenches built along roadways and grassy medians to collect, cool and clean the run-off from the roads. This filtering process removes nitrogen, phosphorous and sediment from run-off that would otherwise flow into the Chesapeake Bay. 

"Bio-swales installed throughout the watershed will treat or offset the impacts of more than 7,700 acres of impervious surfaces and remove over 2,600 tons of sediment, 90,000 pounds of nitrogen and 10,000 pounds of phosphorus from entering waterways annually," according to SHA.
