David Russell is our “most Yankee” transplant here [...]

In November of 2015, work began on a very large project for Sain Associates: the Horizontal Curve project. We kicked off this project with a presentation to ALDOT West Central Region (Tuscaloosa area) representatives where we gave an overview of the project and outlined its purpose. From then on, we have been working around the clock on this major project!
The “horizontal curve project” is a part of one of ALDOT’s many safety initiatives aimed at reducing roadway departure crashes, many of which occur on horizontal curves. A horizontal curve is a very important transition element in geometric design for highways. It provides a transition between two tangent strips of roadway, allowing a vehicle to negotiate a turn at a gradual rate rather than a sharp cut.
This project covers the entire state of Alabama, and Sain’s areas of responsibility are the west central, north, and east central regions. In total, we have 369 sites that require assessment. As a part of this project, we’ve completed individual site assessments along US-72, US-31, SR-76, US-231 and US-431. We are currently about 75% complete with the project. The West Central region is complete, and we are wrapping up the North region this summer. We kicked off the East Central region this month and hope to have it finished in January 2018.
Sain Associates’ Vice President, Becky White, has served as our overall project manager with management assistance from Jennifer Brown, Project Manager, and myself. Other key team members include Charles Cochran, Erin Curry, Jake Balentine, Justin Watson, and David Coggin who have assisted with site visits and report development. Several other staff members in the Birmingham office have been involved as well.
This has been a very large undertaking considering the area covered and the 369 sites to be assessed as part of our work. This is and will continue to be a rewarding project for Sain Associates and staff to have such a huge impact on saving lives on Alabama roads.
