Durham County Bridge No. 110
McCormick Taylor is providing conceptual phase engineering services for the replacement of Bridge No. 110 over Little Creek on SR 1110 (Farrington Road) in Durham County.
The Challenge
The project’s location near Jordan Lake creates environmental sensitivity and regulatory complexity, with the U.S. Army Corps of Engineers (USACE) serving as a key stakeholder. Early coordination with federal, state, and local agencies, as well as municipal, county, emergency services, and tribal representatives is essential for identifying environmental constraints, permitting considerations, and jurisdictional impacts before advancing design. At the same time, multiple alignment alternatives will require evaluation for roadway geometry, bridge feasibility, hydraulic compatibility, and constructability. Establishing stakeholder consensus and defining constraints during the conceptual phase is critical to reducing risk in subsequent project phases.
How We Helped
McCormick Taylor is leading environmental coordination by preparing key mapping deliverables and distributing Landowner Notification, Right-of-Entry, and Start of Study letters to federal, state, and local agencies, including USACE, USFWS, and NCWRC. We are also engaging local stakeholders and submitting data requests for archaeological, historic, geoenvironmental, and traffic information to support the conceptual design.
For the bridge and roadway, McCormick Taylor is developing two functional design alternatives using LiDAR and available survey data. Each alternative will include typical sections, horizontal and vertical alignments, preliminary bridge length, and super-elevation data. We are coordinating closely with our hydraulic subconsultant to confirm alignment feasibility and prepare preliminary bridge layout information, evaluating span, structure type, and constructability.
Results
This conceptual phase provides a strong technical and regulatory foundation for future project phases. Through early coordination with USACE and other stakeholders, McCormick Taylor is helping NCDOT identify constraints, evaluate viable alternatives, and reduce environmental and permitting risks. By delivering two functional design alternatives supported by mapping, data analysis, and stakeholder input, the project will be positioned for informed decision-making, with minimized risk, improved constructability, and early alignment among key stakeholders.
