Regional Transportation Plan Goals

According to the 2045 RTP, this project falls under H-GAC’s Manage, Maintain, and Expand strategies, which collectively directly support all five of H-GAC’s goals of improving safety, achieving/maintaining a state of good repair, moving people and goods efficiently, strengthening regional economic competitiveness, and protecting cultural and natural resources. [1] Improve Safety: This project will provide additional capacity to the roadway and reduce primary and secondary crashes caused by congestion. [2] Achieve & Maintain State of Good Repair: In a widening/reconstruction project, old pavement is removed, and new pavement is constructed, thus increasing the state of good repair. [3] Move People and Goods Reliably and Efficiently: This project will reduce congestion and reduce resulting crashes, increasing the reliability of the facility. [4] Strengthen Regional Economic Competitiveness: This project will reduce congestion and resulting crashes, increasing the truck travel time reliability of the facility, boosting regional and economic competitiveness. [5] Conserve and Protect Natural and Cultural Resources: This project will include improved drainage, which will benefit the natural resources abutting the facility. This project will reduce emissions caused by idling and congestion.

Potential Crash Reductions

1.917

4.473

Crash rates for this segment are per 100 million VMT. The fatality rate is 1.917, higher than the regional average (1.23), and the serious injury rate is 4.473, lower 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. The addition of pedestrian infrastructure will allow pedestrians to safely use the facility and reduce points of conflict with vehicles, thus improving the overall safety of the segment. In addition, the project will include safety improvements as outlined in the IH 45 South Gulf Freeway PEL study. Managed lanes are vital for reducing congestion and offering drivers more reliable timeframes for getting to their destinations, adjusting lane strategies as needed to maximize roadway efficiency, and improving traffic flow on both the managed and general-purpose lanes. The consolidated crash reduction factor for this project is 93%, as a result of installing sidewalks (WC 407) and providing additional travel lanes (WC 517).

Potential Congestion Reductions

Yes

Rank #8, https://www.txdot.gov/apps/statewide_mapping/StatewidePlanningMap.html (Top 100 Layer)

The project will be reconstructing and widening from 8 to 12 lanes (adding 4 managed lanes - WC 517) while also constructing Safety (restriping crosswalks at frontage road intersections - WC 403), operational (intersection improvements on the frontage roads), and mobility improvements (interchange reconfigurations - WC 515 and sidewalks on frontage roads - WC 407) to IH 45 S mainlanes and frontage roads. The segment will be brought up to TxDOT and FHWA safety design standards.

Connectivity to Jobs, Medical Facilities, and Activity Centers

Yes

13,925

Yes

Yes

The project will be reconstructing and widening from 8 to 12 lanes (adding 4 managed lanes) connecting into NHHIP Segment 3 right next to Downtown Houston and EADO. It will be improving connectivity to Downtown Houston (Activity Center and jobs) and UH Campus. St. Joseph Medical Center is nearby the IH 69 interchange. Eastwood Transit Center is next to this project corridor which connects people to jobs as well.

State of Good Repair

Pavement less than 30 years; Bridge is 52 years old (3 years since reconstruction)

Poor

Segments of the project have pavement in Poor condition, according to FHWA guidelines. This segment contains bridges in Fair condition, according to FHWA guidelines. The worst bridge on this project segment was built in 1972 (and reconstructed in 2020). It is rated as being in Fair condition overall, with a superstructure condition score of 6, substructure condition score of 5, and a deck condition score of 6. In a widening/reconstruction project like this project, pavement is removed, and new pavement is constructed, thus increasing the state of good repair and extending the service life of the facility.

Biking and Walking Conditions

Frontage roads will have sidewalks/shared use paths on them per the IH 45 S PEL Study. Shared use paths provide a low-stress experience for active transportation users, increasing user safety and health while improving regional connectivity. The addition of sidewalks will create transportation alternatives and allow pedestrians greater access to services and improve quality of life.

Impacts to Vulnerable Populations

48.8

The area surrounding the project segment has a higher low-income population (24.06%) as compared to the regional average of 13.5%. The area surrounding the project segment has a higher minority population (72.71%) as compared to the regional average of 65% minority. Because of its central location in the regional network, the project will produce improvements in mobility and connectivity for vulnerable populations as well as connectivity to schools, medical facilities, and social services for the regional population. As a result of the improvement, vulnerable populations will have increased resilience and evacuation capacity in the event of hazards. IH 45 S is an evacuation route. The project will improve drainage to ATLAS-14 standards, which reduce flooding events and their impact on vulnerable populations. The project will increase access to and reliability of transit services for vulnerable populations, who generally rely more on these services.

The area surrounding the project segment has a higher low-income population (24.06%) as compared to the regional average of 13.5%. The area surrounding the project segment has a higher minority population (72.71%) as compared to the regional average of 65% minority. TxDOT’s Environmental Process is designed to ensure compliance with Title VI of the Civil Rights Act of 1964, and the Executive Order on Environmental Justice. Standard practice is to implement projects that provide user safety and operational efficiency while taking into account environmental quality and impacts to surrounding communities. In practice this means identifying and assessing potential project impacts, then proposing measures to avoid, minimize and/or mitigate disproportionately high and adverse effects to Environmental Justice Populations. For example, the project will improve drainage to ATLAS-14 standards, which will mitigate impacts from added capacity to vulnerable populations. A noise analysis will be conducted to determine if sound walls are needed or not as part of the NEPA process.
