Centreville Freight Line Emergency Repairs. Millington, Maryland.

Located in Millington, MD this project involved emergency repairs of two sections of track damaged by Hurricane Irene and Tropical Storm Lee in August and September of 2011.

WRA was contracted by the Maryland Transit Administration (MTA) to produce emergency repair plans to allow rail services to resume and prevent additional environmental impacts. Time was of the essence and WRA worked quickly to expedite all services, basing our design upon the use of recycled or readily available materials acceptable to both MTA and the railroad operator, Maryland and Delaware Railroad (MDR). After design of the repairs using a combination of 72-inch and 48-inch RCP culverts, grout bag headwalls and crusher run backfill, WRA expedited an approximately one week bidding process by actively reviewing contractor proposals for alternate materials and construction methods. Repairs were completed by the selected contractor within approximately two weeks, allowing rail services to resume. Permanent repairs using a single-span bridge structure were also subsequently designed by WRA.
