THURMONT, Md. — After having one or both lanes closed for more than a year, Md. 550 (Sabillasville Road) between Eylers Valley Flint Road and Kelbaugh Road north of Thurmont is scheduled to reopen to two-way traffic Wednesday, according to an emailed release from the Maryland State Highway Administration.
The road closed after a mudslide in April 2011 and reopened to one-lane alternating traffic with a traffic signal June 14, 2011. A temporary containment fence was put in place while a permanent one was built.
The SHA put in a containment system which includes an approximately 150-foot retaining wall of concrete panels and steel beams to protect the road from falling rocks, mud, and debris, according to the release.
The wall ranges from 6 to 10 feet tall and also has a 14-foot rock containment fence. A drainage system was also installed to help prevent future erosion of the hillside, according to the release.
The mudslide happened April 16, 2011, following several days of heavy rain and storms.
