Project Information

Agency Name TxDOT Houston District
Project Title SL 8 Widening
Facility/Street/Highway SL 8
Limits From North of US 90 to Woodforest Blvd
Description Widen From 4 to 8 Lanes - The roadway will be expanded from a four-lane facility to an eight-lane facility.
Timeframe Medium Term (6-10 Years)
Estimated Cost $60,400,000.00

Investment Category-Focused Criteria

The project is located in a high growth area. The population is projected to grow by 0.4% and jobs are projected to increase by 12.3%. Some residential land use changes have been announced or modeled. This section of SL 8 is congested. In the 2022 report 100 Most Congested Roadways in Texas by the Texas Transportation Institute, the annual total delay per mile on the segment is 14,872 person hours. The current daily volume of traffic on the segment is roughly 59,523, of which 12.9 percent are trucks. By 2041 daily traffic volume is expected to increase by 40 percent. Intersection improvements and traffic signal timing optimization are being implemented on this project to improve traffic operations. The purpose of the project is to improve capacity, connectivity, level of service, and safety of the project segment. The added capacity will improve regional connectivity for all modes while also reducing congestion and improving safety by reducing primary and secondary crashes due to congestion and by bringing the segment of SL 8 up to TxDOT and FHWA safety standards.

This project will widen From 4 to 8 Lanes - The roadway will be expanded from a four-lane facility to an eight-lane facility to match the segment to the south coming off the new BW 8 bridge over the Ship Channel.

Yes

The project is located in a high growth area. The population is projected to grow by 0.4% and jobs are projected to increase by 12.3%. Some residential land use changes announced or modeled. There are some warehouses being constructed along US 90 nearby this project corridor as well, this project will improve Port of Houston access to them.

Yes

This project will add capacity. Adding capacity will relieve congestion on the facility by allowing for a reduced vehicle to capacity ratio. Further, it will allow more room for traffic to avoid crashes on the segment, reducing congestion caused by crashes.

LOS A

Yes

Uvalde Rd and Dell Dale Street both run parallel to SL 8 or even IH 610 E and SH 99 run parallel to this segment of SL 8 and could be used as an alternative in the event it needs to be closed or vice versa.

Yes

This section of SL 8 is congested. In the 2022 report 100 Most Congested Roadways in Texas by the Texas Transportation Institute, the annual total delay per mile on the segment is 14,872 person hours.

Frontage road sidewalks will be constructed as possible. The addition of sidewalks will create transportation alternatives and allow pedestrians greater access to services and improve quality of life.

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

The project will widen lanes to allow more space to move disabled vehicles and to better maintain flow on the facility after vehicle collisions.

The pavement on this facility is mostly in Good condition, according to TxDOT and FHWA guidelines. 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. The project segment contains 1 bridge in Fair condition. It was built in 1988. It is rated as being in Fair condition overall, with a superstructure condition score of 7, substructure condition score of 7, and a deck condition score of 6. The project includes reconstruction of the roadway which will lead to an improvement in the state of good repair and extend the service life of the facility.

Planning Factors Criteria

0.737

0.982

Crash rates for this segment are per 100 million VMT. The fatality rate is 0.737, lower than the statewide average (1.23), and the serious injury rate is 0.982, lower than the statewide average, (6.18). To further enhance safety, the widening of the roadway will provide additional capacity to the roadway and reduce primary and secondary crashes caused by congestion. Additionally, in line with the project management guidelines, the consideration of frontage road sidewalks is underway, with the schematic expected to be ready by mid-July 2023. The consolidation crash reduction factor for this project is 93% as a result of providing additional travel lanes (WC 517), and providing pedestrian and bicycle infrastructure (WC 407).

The area surrounding the project segment has a higher low-income population (15.37%) as compared to the regional average of 13.5%. The area surrounding the project segment has a higher minority population (90.14%) 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. SL 8 is an evacuation route. The project will improve drainage to ATLAS-14 standards, which reduce flooding events and their impact on vulnerable populations.

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.

Impacts on Natural and Cultural Resources

This project is currently classified as a type of action that qualifies as a “Categorical Exclusion” as it is not expected to have a significant effect on the human and natural environment. If through the environmental analysis process TxDOT determines that the proposed action does not qualify as a CE, then an Environmental Assessment (EA) would be prepared to identify, mitigate and avoid impacts to natural and cultural resources
