CTRMA Manor Expressway – US 290 E Tollway Phase I

Tollway extending from US183 to SH130
State Agency
Drainage Impact Analysis & Design of Drainage Improvements
Quick Facts
  • The project is five miles of tollway
  • There are five riverine bridges in the corridor
  • The project became a design-build delivery

The US 290 E project crosses four watersheds: Little Walnut, Walnut, Decker, and Gilleland creeks. KFA prepared existing and proposed condition hydrologic and hydraulic models using HEC-Hydrologic Modeling System and HEC-River Analysis System, respectively, to quantify the relative impact of the project at three dozen points of interest. KFA performed hydraulic analysis of all cross culverts and bridges to prepare recommendations for structures.  A key aspect of the project was continual interdisciplinary coordination among the three segments of the project.  KFA prepared the preliminary design report to state methods, findings, and recommendations for improvements and impact mitigation measures.
