Roadway Design

Spectrum Drive Improvements

Frederick County Department of Public Works

In order to improve traffic capacity, operation and vehicular flow, BAI provided engineering services for the reconstruction of Spectrum Drive, Holiday Drive and Lowes Lane, beginning at the intersection of MD Route 85.  The project involved extensive preliminary planning for the road network, including roadway widening, intersection alignment, commercial access (to the Francis Scott Key mall), roundabout,traffic signalization and mall parking reconstruction.

In cooperation with the Frederick County Department of Public Works, BAI initially provided traffic engineering analysis, including Synchro/SimTraffic modeling and simulation, vehicle queue determination, traffic signals and roundabout alternative, capacity projections, level-of-service, and vehicle and pedestrian safety investigations.  Engineering design services included the development of complete construction plans, specifications and cost estimates for roadway improvements involving: grinding and pavement overlay, full-depth pavement widening, drainage improvements, continuous curb and gutter and concrete sidewalk throughout the project, a roundabout at the intersection of Spectrum Drive and Holiday Drive East, stormwater management and permitting, and erosion and sediment control.

BAI provided traffic signal design services for the intersections of Spectrum Drive at Holiday Drive East, Lowes Lane and at the Mall Entrance.  Detailed phased construction plans were prepared in order to maintain vehicular access to the mall during construction.

MD Route 51 Reconstruction

Maryland State Highway Administration, District 6 Office

In cooperation with the Maryland State Highway Administration,  BAI was responsible for the reconstruction and rehabilitation of a half-mile of MD Route 51/Industrial Boulevard from West 3rd Street to Pennsylvania Avenue.

MD Route 51/Industrial Boulevard was originally rehabilitated in 2006.  However, due to deterioration of the underlying pavement, there is need to repair the pavement and install new curb and gutter.  There is also a need to verify ADA compliance for all the sidewalks and sidewalk ramps within the project limits, and upgrade to current standards as necessary.

This project included development of construction plans, specifications and cost estimates and involved pavement mill, overlay and full reconstruction, curb and gutter, inlet modifications, sidewalks and ADA compliant ramps, roadside safety grading, stormwater management, erosion and sediment control, work zone traffic control, and pavement markings and signing.
