Alternatives for Workshop
This is a PDF Attachment, double click to view:March 2016: Alternative 1 - No Build March 2016: Alternative 1 - No Build

Alternative 1 includes no major improvements and serves as a baseline for comparing the impacts and benefits associated with the build alternatives. Minor short-term improvements would occur as part of routine maintenance and safety operations. However, this Alternative does not address the purpose and need for the project.
This is a PDF Attachment, double click to view:March 2016:  Alternative 2 - Two Lanes with Existing Bridge (TSM/TDM) March 2016: Alternative 2 - Two Lanes with Existing Bridge (TSM/TDM)

The alternative, commonly known as the Transportation System Management and Transportation Demand Management (TSM/TDM) alternative, proposes to investigate managing and optimizing the existing facilities to increase efficiency, and explore ways to manage traffic demands. The types of TSM improvements may include signal timing improvements and synchronization and queue storage extensions. The types of TDM improvements may include strategies that promote and improve access to ride-share and available transit options.
This is a PDF Attachment, double click to view:March 2016:  Alternative 3 - Four Lanes on Existing Bridge March 2016: Alternative 3 - Four Lanes on Existing Bridge

This alternative proposes a four-lane roadway section between MD 471 and MD 246 with 12-foot outside travel lanes, 11-foot inside travel lanes. Minor roadway widening and reconstruction would be proposed to accommodate the additional lanes. The bridge would remain in place, and the roadway would be restriped to accommodate the additional lanes. No major improvements to bicycle or pedestrian facilities would be proposed.
This is a PDF Attachment, double click to view:March 2016:  Alternative 4 - Four Lanes on New Bridge with Sidewalks March 2016: Alternative 4 - Four Lanes on New Bridge with Sidewalks

This alternative proposes a four-lane roadway section between MD 471 and MD 246 with 13-foot outside travel lanes for shared bicycle and vehicular use, 11-foot inside travel lanes, curbs, and ADA-compliant 5-foot sidewalks. The bridge would be replaced in the same location with a slightly wider structure to accommodate the proposed roadway width and ADA-compliant sidewalks. The outer through lanes would be bicycle-compatible shared-traffic lanes. The posted speed for MD 5 would be lowered from 45 mph to 35 mph in order for the proposed design changes of this alternative to comply with accepted engineering practice.
This is a PDF Attachment, double click to view:March 2016:  Alternative 5 - Five Lanes on New Bridge with Sidewalks March 2016: Alternative 5 - Five Lanes on New Bridge with Sidewalks

This alternative proposes a five-lane section with four 11-foot travel lanes, a 12-foot center-turn lane, 5-foot shoulders, which can accommodate bicycles, curbs, and 5-foot sidewalks, compliant with Americans with Disabilities Act (ADA). The existing bridge would be replaced with a wider and longer structure that would accommodate the five roadways lanes, shoulders, and sidewalks at a higher elevation to reduce flooding. The posted speed for MD 5 would be lowered from 45 mph to 35 mph in order for the proposed design changes of this alternative to comply with accepted engineering practice.
This is a PDF Attachment, double click to view:March 2016:  Option 1 - Relocated MD 471 (400 Feet West) March 2016: Option 1 - Relocated MD 471 (400 Feet West)

This option would shift the existing intersection of MD 5 and the north leg of MD 471 approximately 400 feet west of its current location to a new signalized intersection. Access from MD 5 to the existing Great Mills Trading Post would remain as a right-in/right-out only. The existing southern leg of MD 471 would remain in place with a modified traffic signal, which would be coordinated with the existing signal. This option would eliminate the acute skew angle of the MD 471 north leg, and it would provide additional distance between this intersection and the MD 246 intersection, improving traffic operations.
This is a PDF Attachment, double click to view:March 2016:  Option 2 - Relocated MD 471 (1100 Feet West) March 2016: Option 2 - Relocated MD 471 (1100 Feet West)

This option would shift the existing intersection of MD 5 and the north leg of MD 471 approximately 1100 feet west of its current location to a new signalized intersection. The existing southern leg of the intersection, Flat Iron Road, would remain in place with a modified traffic signal. The new intersection with MD 471 north leg would be signalized, but would allow eastbound traffic to free-flow without a stop signal. This option would eliminate the acute skew angle of the MD 471 north leg, and it would provide additional distance between this intersection and the MD 246 intersection, improving traffic operations.
This is a PDF Attachment, double click to view:March 2016:  Option 3 - Close Old Great Mills Road Access to MD 5 March 2016: Option 3 - Close Old Great Mills Road Access to MD 5

This option closes the existing right-in/right-out intersection of Old Great Mills Road and westbound MD 5. This would eliminate an existing signal and traffic conflict point. The existing intersection at the northern end of Old Great Mills Road with MD 246 would be retained without modification, allowing full access for vehicles to the existing businesses.
