RM 3237 and RM 150 Roundabout

Wimberley, Texas

The project consists of replacing a T-Intersection with a more efficient and safer roundabout design at the intersection of RM 150 and RM 3237. American Structurepoint performed preliminary engineering and has developed engineering plans, specifications, and estimates (PS&E) to replace the intersection and save three heritage trees. Improvements also include drainage of the intersection and replacement of several culverts. Texas Commission on Environmental Quality (TCEQ) coordination and coordination with the TxDOT South Travis Area office was required for approval of the Water Pollution Abatement Plan. Utilities have been coordinated to be relocated before letting. American Structurepoint’s drainage engineers worked with the utility coordinator to avoid a conflict with an existing buried underground telecom line and the ditch flow line. The solution to riprap the channel at the utility to protect it in place saved the client $8,000 in utility relocation costs.
