​Crews to Repair Deteriorated MD 100 Bridge Decks at MD 2 Interchange During Four Weekends; Drivers Should Plan for Additional Travel Time and Detours 

(September 12, 2023) – The Maryland Department of Transportation State Highway Administration will begin a multi-weekend bridge rehabilitation and repair project on Friday, September 15 on the two MD 100 bridges over MD 2 (Governor Ritchie Highway) in Anne Arundel County. The project limits extend from the Oakwood Road overpass to MD 10 (Arundel Expressway)​. All work is scheduled for completion by the second weekend of October, weather permitting.​​

This project has been delayed and new dates are added below.

Starting Friday night, crews will place concrete barriers to enable crews to safely perform the work in a shortened timeframe. Crews will work for four weekends and close and detour ramps Fridays through Mondays 9 p.m.-5 a.m. Weeknight MD 100 lane closures, Sunday through Thursday nights from 9 p.m. to 5 a.m., are also permitted if needed. Drivers will be guided with the following work zone temporary lane closures and ramp detours:

Weekends of September 15-18 and September 22-25 (Eastbound MD 100)

New dates: September 29-October 2 and October 6-9​

  • Crews will temporarily close the southbound MD 2 ramp to eastbound MD 100 from 9 p.m. Friday through 5 a.m. Monday for two weekends.
  • Drivers will be guided along a signed detour each weekend directing traffic to eastbound MD 100.

Weekends of September 29 – October 2, and October 6 - October 9 (Westbound MD 100)

New dates: October 13-16 and October 20-23​

  • ​Crews will temporarily close the ramp from northbound MD 2 to westbound MD 100 from 9 p.m. Friday through 5 a.m. Monday for two weekends.
  • The ramp from northbound MD 2 to westbound MD 100 will be closed; drivers will be able to use the right turn movement from northbound MD 2 to access eastbound MD 177 toward Gibson Island.
  • The ramp from MD 177 (Mountain Road) onto westbound MD 100 will be closed.
  • The ramp from northbound MD 10 to westbound MD 100 will be closed. 
  • Drivers will be guided along a signed detour each weekend directing traffic to westbound MD 100.

Work includes removing existing pavement, patching, and pouring the concrete decks, waterproofing the bridge decks, asphalt bridge approach paving, and concrete repairs to the curbs and barriers of each bridge. Crews will work on site for the duration of each weekend, and then open lanes for weekday travel. 

Portable variable message signs will be in place along MD 2, MD 100, and MD 177 providing advance notification of all travel impacts for the bridge work. State Highway Administration’s contractor Concrete General Inc. of Gaithersburg will use arrow boards, signs, cones, and barrels to safely guide drivers through the work zone and along the designated detours. 

The State Highway Administration understands temporary ramp and lane closures can be an inconvenience, but this work is necessary to ensure a safe and reliable transportation system. Motorists are asked to reduce speeds approaching and while in active work zones.  Drivers are asked to stay alert, stay focused, look for reduced speed limits as well as driving pattern changes, and slow down in construction zones. 

Automated speed enforcement is part of the MD 100 Bridge Rehabilitation Project; the work zone speed limit is 55 mph and civil penalties may be issued at the start of work. Information about the Maryland SafeZones program is available at https://www.safezones.maryland.gov​. Customers who have questions may contact the District 5 Office at 410-841-1000 or toll-free at 1-800-331-5603. 

Motorists in need may dial #77 on their mobile devices for roadside assistance.
