For this project, Sain Associates obtained topographic information at each overhead and post-mounted Interstate Guide Sign in place on Interstate 85 and Interstate 65 along lanes in each direction through Autauga, Butler, Elmore, Lowndes, Macon, and Montgomery Counties.
The survey also included signage on connecting access roads and overpasses along Interstate 65 and Interstate 85.
Sain located bridge mounted, cantilever, butterfly, overhead and any ground mounted signs with GPS. We staked bore hole locations, marked elevations and took cross sections at each sign location.
We compiled and delivered a digital file to the Alabama Department of Transportation for their use in maintaining and managing signs along these routes.
