SH 199 at IH 820 Interchange

CobbFendley is providing preliminary engineering services for developing a design schematic of this multilevel interchange project. The project includes developing multiple alternative layouts in order to select a preferred alternative consisting of mainlanes, ramps, frontage roads, direct connectors, collector-distributor roads. The project also includes public involvement, value engineering study, data collection analysis, drainage, conceptual traffic control, traffic engineering/operations/simulations, 3-D modeling, and subsurface utility engineering. CobbFendley is leading and performing geometric design for interim and ultimate improvements, evaluating right-of-way needs, coordinating with team members and TxDOT, attending meetings, identifying and resolving design issues, preparing Design Criteria and Technical Memos, and performing quality assurance and quality control procedures.
