We’re proud to announce that the Contee Road Realignment and Reconstruction Project is the recipient of the 2018 CEAM Large Project of the Year Award. Recognizing projects that demonstrate responsiveness to citizens' needs, cost effectiveness, and innovative use of County staff and funds, the award will be presented September 20 at the County Engineers Association of Maryland’s Fall Conference. Located in Prince George’s County, MD, this 1.14-mile-long project was the top priority of the County to connect I-95 to the U.S. 1 corridor, and was developed as a four-lane, divided, closed-section, urban arterial within a maximum 120-foot right-of-way.

The Contee Road corridor was plagued with high volumes of traffic, narrow or non-existent shoulders, deficient sight lines, and many residential and commercial access points, which allowed little room for additional economic and residential development. This project introduces a more direct route for vehicular traffic and will help with the overall systematic connection of multiple transportation facilities in the area, including the Intercounty Connector (ICC), I-95, and U.S. 1. Additionally, the realigned Konterra Drive and the new Contee Road Interchange over I-95 are a critical component of Prince George’s County’s short- and long-term economic growth plans.

McCormick Taylor’s traffic engineers were responsible for a comprehensive traffic impact statement (TIS) review and supplemental proposed traffic assessments to identify potential impacts of this proposed roadway widening and extension.


To supplement the TIS, trip generation and assignment were performed for the existing land uses along Contee Road to assist with determining additional signalization along the corridor. Multiple Synchro models and SimTraffic simulations were prepared to evaluate several design concepts, determine proposed lane configurations, and address future pedestrian and bicyclist movements between residential areas, parks, schools, and shopping areas. Based on the analyses and planning efforts, McCormick Taylor refined the preferred concept to develop a proposed typical section that incorporated vehicular, pedestrian, and bicycle amenities.
