Project Information

Agency Name TxDOT Beaumont District
Project Title SH 146 Widening
Facility/Street/Highway SH 146
Limits From IH-10 south to Cedar Bayou
Description Widen from 4 to 6 lanes
Timeframe Medium Term (6-10 Years)
Estimated Cost $100,000,000.00

Investment Category-Focused Criteria

Existing traffic shows a LOS C/D for existing peak hours and project to have LOS E/F in 2035. Approximately 19% of vehicles are truck traffic within the area. SH 146 is a major north-south thoroughfare and the surrounding areas are growing and increasing employment and freight traffic along the corridor.

The project will be reconstructing and widening from 4 to 6 lanes (adding 2 through lanes and installing continuous turn lane) while also constructing Safety (install pavement markings), and operational improvements(install signals and improve signals). The segment will be brought up to TxDOT and FHWA safety design standards.

Yes

The project proposes access management changes throughout the corridor to improve connectivity to existing and proposed developments and improve traffic operations and safety.

Yes

SH 146 is a major north-south corridor for freight, industrial, and employment on the east side of the Houston metropolitan area. Widening SH 146 will help to maintain, and in some areas improve, existing LOS to meet minimums and allow the movement of people and goods to occur effectively and efficiently.

Other Investment Category Focused Criteria

Yes

The daily traffic on this roadway segment is over 33,000 vehicles per day and it continues to increase. This project will improve connectivity, ease congestion, and reduce travel time on this segment of SH 146. The additional capacity will improve freight access to many major freight generators in the region including the region’s seaports and manufacturing facilities and many freight warehouses. The project will improve operations for the regional network by reducing congestion (improving the level-of-service) on SH 146 and improving the connections between other parts of the roadway network.

Pedestrian and bike accommodations will be included in accordance with TxDOT's Roadway Design Manual. This would include sidewalks at a minimum.

No existing or planned transit service is provided on this facility.

The proposed project will reduce inoperability from vehicular crashes or potential storm damage by providing additional lanes of travel. The proposed facility will be less prone to complete closure because of the added capacity. Access management strategies such as selective placement of raised medians should reduce vehicular collisions.

This project will improve the state of good repair and extend and improve the service life and resiliency of the facility by adding newly constructed sections and reevaluating any existing pavement that may remain to bring it up to the current standards. The pavement design for the new sections and any existing sections will be based on the latest traffic data and design standards. The drainage facilities for the project will be designed to meet or exceed ATLAS-14 standards. With this newly constructed / reconstructed section minimal maintenance work should be required for several decades.

The proposed project reduces expected fatality and serious injury crashes by building to current design standards with 12' travel lanes and 10' outside shoulders and a 14' - 16' center left turn lane. The proposed design would include additional through lanes, a continuous turn lane, and edge line rumble strips or profile pavement markings.

Resiliency

High

Model.HighGrowthAreaNeedsQuestionnaire.Resiliency2

The proposed project would reduce the vulnerability to flooding as it would be built to current hydrologic and hydraulic design standards. It would be designed to meet or exceed ATLAS-14 drainage standards. Specific improvements may include additional cross drainage capacity and possibly raising the proposed roadway profile if determined necessary by the hydraulic analysis.

By adding capacity, the proposed project should reduce traffic congestion and help minimize travel delays. This added capacity project should improve connectivity to and from the numerous employment opportunities along this corridor in both Chambers and Harris Counties. The additional through lanes and center turn lane should help improve safety along this stretch of roadway. The project would provide accommodations for pedestrian and bike traffic in accordance with TxDOT's Roadway Design Manual. This along with signal improvements at the cross streets for pedestrian movements will provide for safer pedestrian use.

The footprint of the proposed roadway improvements would be minimized to help prevent impacts to adjacent properties, thus reducing any possible displacements of persons, businesses, etc. The current roadway usage would not change with the proposed construction project. The addition of through lanes would maintain access to adjacent properties including public and private facilities and services with less impact to the flow of traffic than currently occurs.

Impacts on Natural and Cultural Resources

Sections of this project are within a flood plain or floodway and wetlands are present. During project development, wetland information is provided to the design team to determine where the project might impact Waters of the U.S. (WOUS). The design is adjusted if possible to avoid and minimize impacts to WOUS. Any unavoidable impacts are mitigated through USACE approved mitigation banks. With regard to the floodplain present, the project would be designed to have no negative impact to the floodplain. No historical sites are located within the project limits and no archeological sites are believed to be present. A thorough investigation into cultural resources is conducted during project development and, if present, the locations are provided to the design team to avoid. Review and coordination of this project would follow approved procedures for compliance with Federal and State laws.
