US Route 222 Reconstruction, Preliminary Engineering

Drive is providing traffic engineering support for the preliminary and final design phases for the total reconstruction of US Route 222 from US Route 30 to PA Route 772 in Manheim and West Earl Townships, Lancaster County. Services include traffic data collection and processing, traffic modelling, traffic analyses, development of preliminary signing and pavement marking design plans, and preliminary engineering cost estimates. Data collection consisted of 24-hour volume counts along US Route 222, US Route 30, and various on- and off-ramps through utilizing Miovision cameras at key locations within the project area; travel time runs were also performed. Traffic modelling and analysis include generating Vissim models to determine potential traffic-related impacts associated with various potential interchange configurations that could be constructed based on the feasibility analysis completed. The results of these traffic analyses were used to develop recommendations for the ultimate interchange configuration along with the signing and pavement marking designs associated with the construction of the proposed interchange.
