US 1 ADA, Sidewalk, and Safety Improvements:
Albion Rd to Paint Branch Pkwy.
Prince George’s County, MD

Sabra & Associates, Inc.  (SAI) has provided design services for the US 1 project that included:


  • Roadway and Streetscape Design


  • Evaluated existing ramps, upgrade to meet SHA ADA design standards and provide ramp details
  • Evaluated existing sidewalks, curb and gutter, medians and driveways (where the curb crosses a pedestrian path) and recommended replacement
  • Evaluated existing inlets and recommended improvements if they are structurally damaged
  • Replaced concrete cross walks at intersections with HMA cross walks
  • Developed quantities and cost estimate
  • Provided design support during construction
  • Upgraded pedestrian ramps, sidewalks, and driveways
  • Installation of detectable warning surfaces
  • Design of intersection islands to meet the latest ADA design guidelines, MDSHA design criteria, “SHA Accessibility Policy & Guidelines for Pedestrian Facilities along State Highways dated December 2005” and “Americans with Disabilities Act Accessibility Guidelines (ADAAG).”

SAI also investigated the existing fire hydrants and utility poles within sidewalks that are in conflict with the aforementioned design guidelines. In cases of design conflicts, SAI proposed alternatives, such as providing bump-outs to avoid relocating fire hydrants and utility poles. Such recommendations were summarized by preparing ADA waiver applications that were submitted to MDSHA for review and approval. SAI was also responsible for:


  • Roadway construction bid documents for milling and resurfacing
  • Upgrading and investigating existing storm drain pipes,
    inlets and manholes, and MOT design
  • Preparing erosion and sediment control plans, and SWM management, design and analysis.
