TxDOT's Bryan District is currently developing design concepts to improve the intersection of US 290/SH 36 in Brenham, Texas, Washington County. While it is early in the process, only preliminary concepts have been developed. Concepts may be added or removed from further consideration and development. Specific alternatives have not been finalized. 

Background

The US 290/SH 36 interchange is one of the busiest interchanges in Washington County. It serves as an important local, regional and statewide roadway connection. The project would improve safety, reduce congestion, maintain connectivity and improve mobility. The primary focus is to construct a new interchange that will provide a continuous US 290 route, maintain two lanes in each direction and maintain access to local roads.

Project Goals

  • Improve safety
  • Reduce congestion
  • Improve regional mobility and local mobility 
  • Maintain connectivity 
  • Provide continuous flow on US 290
  • Minimize impacts

Project Overview

The primary focus is to improve the US 290/SH 36 interchange and will include proposed changes along US 290 west of the interchange near Berlin Road as well as south of the interchange to the BSNF railroad turn around. Three concepts were originally presented and shared with Brenham City Council/Washington County Commissioners Court in March 2019. TxDOT continued to analyze the interchange resulting in two additional concepts for a total of five concepts that meet the primary focus of the project. A preferred alternative would be based on the following five concepts.

All concepts include:

  • Expanding US 290/SH 36 connection from one to two lanes 
  • Completing conversion to one-way frontage roads
  • Updating entrance and exit ramps to current standards
  • Accommodating bicyclists and pedestrians within urban settings

Concept A: Diverging Diamond Interchange - March 2019

  • Constructs a Diverging Diamond Interchange (DDI) at the intersection of US 290 and SH 36 which eliminates the need for left‐turning vehicles to cross paths of approaching vehicles by directing traffic to the opposite side of the road across the interchange
  • Constructs an R-Cut (Restricted Crossing, U-Turn) intersection design for US 290 and Westwood Lane which improves safety by removing the straight-thru, left-turn conflicts at the intersection
  • Handles traffic efficiently by including traffic signals within the DDI and R-Cut intersection at Westwood Lane
  • Maintains similar "footprint" as the existing interchange and requires the least amount of right of way to construct 

Revised Concept B: Central Direct Connect - March 2019, revised November 2020

  • Constructs a new two-lane roadway alignment in each direction just south of the existing US 290/SH 36 intersection
  • Includes an uninterrupted direct connection providing continuous flow along US 290
  • Provides a direct connect tie-in west of Westwood Lane
  • Reconfigures the existing US 290/SH 36 intersection to accomodate local access
  • Requires some right of way

Concept C: Split, Northern Connection - March 2019

  • Constructs a new westbound two-lane roadway alignment north of the existing US 290/SH 36 interchange and a new eastbound two-lane roadway alignment just south of the existing 290/SH 36 interchange
  • Includes an uninterrupted direct connection providing continuous flow along US 290
  • The eastbound direct connect ties in west of Westwood Lane and the westbound direct connect ties in near Berlin Road
  • Reconfigures the existing US 290/SH 36 intersection to accommodate local access
  • Requires right of way 

Concept D - Northern Connection - November 2020

  • Constructs a new two-lane roadway alignment in each direction north of the existing US 290/SH 36 Intersection
  • Includes an uninterrupted direct connection providing continuous flow along US 290
  • The direct connect ties in near Berlin Road and would construct an overpass at Berlin Road with u-turns for improved safety and connectivity
  • Reconfigures the existing US 290/SH 36 intersection including a frontage road connection between Business 290 and Old Mill Creek Road to accommodate local access
  • Requires right of way

Concept E - Southern Connection - November 2020

  • Constructs a new two-lane roadway alignment in each direction south of the existing US 290/SH 36 Intersection 
  • Includes an uninterrupted direct connection providing continuous flow along US 290
  • The direct connect ties in near Berlin Road and would construct an overpass at Berlin Road with u-turns for improved safety and connectivity, as well as an overpass at Old Mill Creek Road with u-turns, as needed.
  • Maintains the existing US 290/SH 36 intersection to accommodate local traffic (Note: Regional main lane traffic will continue on US 290 through the direct connect, thereby reducing the traffic on the existing US 290/SH 36 intersection improving its operation.)
  • Requires right of way

Next Steps

  • Continue to receive comments and review feedback
  • Continue evaluating and refining concepts to determine alternatives
  • Develop outreach plan and continue identifying stakeholders
  • Select alternative and develop a preliminary design schematic
  • Conduct environmental studies on selected alternative
  • Tentative start of construction upon approval: 2025

Get Involved

Public involvement will be an ongoing process.
