MD 2/4 (SOLOMONS ISLAND ROAD) PHASE II FROM FOX RUN BOULEVARD TO SOUTH COMMERCE LANCE WIDENING

Calvert County, MD

McCormick Taylor completed the design to improve traffic operations and enhance safety and mobility for motorists, bicyclists, and pedestrians along MD 2/4 (Solomons Island Road) between Fox Run Boulevard and Commerce Lane in Prince Frederick, MD.

INFRASTRUCTURE

 

The Challenge

MD 2/4 is a major corridor that provides access to the southern region of Maryland. Since its construction, there has been an increase in development along the roadway as well as daily commuters traveling to other areas of the region. With continued development anticipated in Calvert County, MD 2/4 required improvements to improve safety, capacity, and accommodations for pedestrians and bicycles. These improvements needed to be completed without causing disruption to the local, region, and state operations which use the corridor every day. The existing roadway included two through lanes, intermittent auxiliary lanes, and minimal pedestrian and bicycle facilities.

 

How We Helped

McCormick Taylor provided a wide range of design and construction support services for this complex project, which included highway design; stormwater management and drainage design; hydrologic and hydraulic analyses for culverts; stream and channel stabilization design; erosion and sediment control design; permitting; MOT; signing; marking; and signalization design. As part of the design, our team provided pedestrian and bicycle facilities along the project corridor to provide separated facilities from the roadway. Prior to construction, there was no sidewalk and minimal shoulders non-motorists could use when traveling along the corridor.

 

McCormick Taylor also assisted with significant coordination and communication efforts between MDOT SHA and the project's stakeholders throughout the design process. Monthly partnering meetings were held in addition to the monthly utility company coordination meetings. These meetings were critical in fostering and continuing the communication and coordination process between Calvert County, MDOT SHA, and all other stakeholders to introduce potential issues with the design, scheduling, submissions, and reviews.

To accommodate ongoing development within the region, McCormick Taylor worked with MDOT SHA, Calvert County, and developers to incorporate future development into the proposed design. The improvements included providing a deceleration lane and access points to accommodate an entrance to a property that was to be developed. Our team also worked closely with several businesses to reconstruct their existing entrances to accommodate the MD 2/4 improvements while minimizing impact, parking, and access issues to the business. Proactive coordination and continued design refinement for these businesses was a key component to project success.

 

During construction, maintenance of traffic was completed by maintaining the existing through lane capacity. This was accomplished by full-depth pavement widening on the outside while maintaining the existing lanes to the inside with temporarily reduced lane widths. With the outside lanes completed, traffic was shifted to the new lanes so that the median work could take place. By minimizing traffic disruption, traffic was able to continue to move through the corridor.

 

Construction phase services included involvement in partnering meetings and coordination design revisions for various field conditions. McCormick Taylor also performed shop drawing reviews and respond to contractor’s questions.

 

Results

The MD 2/4 is an excellent example of how McCormick Taylor achieved transportation network goals while also incorporating local needs into the project. The existing roadway was widened to provide three through lanes and a continuous auxiliary lane along with sidewalks and bike lanes on both sides of the roadway. With the completion of the project, MD 2/4 provides better regional connections as well as improved accessibility, mobility, and safety for all roadway users.
