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

Regional Transportation Plan Goals

Widening SH 146 and improving intersections through added safety measures and installing additional signals help to improve safety along the corridor. Improved visibility for existing signs and pavement markings will also improve safety along the corridor. Widening the road and also providing a mill & overlay (or a reconstruction depending on existing pavement) improves the exisitng facility to be in GOOD condition and increase the state of good repair. SH 146 is not a corridor with transit options, but the project proposes added sidewalk connectivity creating opportunity for bike/ped movements. The widening will also improve freight movement to and from the industrial and commercial centers along SH 146. The movement for these vehicles will improve as congestion eases through added capacity and traffic operations improves. Finally, widening will be done within existing ROW.

Regional Significance

Roadway

Principal Arterial or Higher Functional Class

Potential Crash Reductions

1.3

7.91

Crash rates for this segment are per 100 million VMT. The fatality rate is 1.3, higher than the regional average (1.23), and the serious injury rate is 7.91, higher than the regional average, (6.18). The reconstruction and widening of the roadway will provide additional capacity to the roadway and reduce primary and secondary crashes caused by congestion. Additonally, the project will add safety, operational and mobility improvements. Signalized intersections will be constructed and refined to improvement corridor wide operations as well as enlarging shoulders to provide for bike/ped to more safely use the facility. The consolidated crash reduction factor for this project is 105%, as a result of improving signals (WC 108) and installing a continuous turn lane (WC 518) and widening the paved shoulders (WC 536)

Potential Congestion Reductions

No

1.25 – 1.50

Travel Time Index (TTI) is a ratio that compares peak period travel times along a corridor to average travel times, thus estimating a relative level of rush hour congestion. Current TTI for the project area is between 1.25, indicating that it takes 1.25 times as long to travel this corridor in the peak period than average, which is mildly congested. Congestion comes from heavy truck traffic and busy industrial area with movement of freight. Heavy traffic during AM and PM Peaks with work commuters

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.

This section fo SH 146 will be reconstructed and have added capacity (additional through lanes) to address congestion and improve mobility. This corridor connects with IH 10 E and FM 1405, providing access to multiple industrial parks and jobs within the Baytown area. The north section of this project has a large shopping center which drives trip generation from the existing residential developments along SH 146 and the added capacity will help convey traffic and to those destination points.

State of Good Repair

Over 40 years

Poor

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.

Biking and Walking Conditions

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

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.
