Locally Preferred Alternative: Four to Six-Lane Managed Technology Corridor (Right-Running Transit) Based on the results of the screening process and input from project partners and stakeholders, the locally preferred alternative for East Lancaster Avenue from Riverside Drive to IH-820 is a six-lane managed technology corridor. Due to ROW constraints, the locally preferred alternative for the segments between Main Street and Riverside Drive and from IH-820 to Dottie Lynn Parkway is four- lanes with shared transit that incorporates all the other elements of Tech-Based Rapid Transit. The locally preferred alternatives were selected due to their ability to reduce crashes, maintain acceptable traffic operations, and accommodate a flexible tech-based rapid transit service. Please note that the final roadway configuration is subject to NCTCOG and TxDOT design and environmental review. Long-term capacity improvements and needs will be determined by TxDOT.
