This project will improve traffic flow on SH 146 at IH-10 by adding a combination through & left turn lane northbound and southbound under IH-10. This will increase the turning capacity from SH 146 to IH-10 along with the capacity of SH 146 at IH-10. This will directly improve the flow of freight at this high-traffic intersection allowing truck traffic to more quickly enter on to IH-10. The improvements will also help reduce congestion at this intersection.

Other Investment Category Focused Criteria
The daily traffic on this roadway segment is over 33,000 vehicles per day and it continues to increase. This project will improve connectivity by easing congestion and reducing travel time on SH 146 through the IH-10 intersection. The additional turn lanes at IH-10 will help truck traffic access IH-10 more efficiently.
Over the past decade, the areas of Mont Belvieu and Barbers Hill have grown significantly and they continues to grow. There has been substantial commercial investment along SH 146 near IH-10 and the growth/development in this area is not slowing. This project will alleviate future congestion due to current and future economic development by adding additional capacity to SH 146 at IH-10.
Sidewalks will be provided in the IH-10 - SH 146 intersection as necessary to connect sidewalks along SH 146 south of IH-10 to future planned sidewalks north of IH-10.
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. The increased capacity should also help reduce the number of accidents and improve the response time of emergency responders.
The pavement section for the proposed new lanes would be built to current design standards based on the latest traffic data and the new lanes would have a service life of several decades with minimal maintenance needed.

Drainage design for this project would be based on Atlas -14. Possible drainage improvements include adding inlets, widening existing inlet throats, and possibly adding drainage pipe (or upsizing existing pipe).

Adding turn lanes at the intersection with IH10 will improve the flow of traffic benefitting all area roadway users. SH146 will continue to increase in traffic use and providing these lanes will improve the safety and access to businesses along SH146.
The current roadway usage would not change with the proposed construction project. The addition of through lanes would maintain access to properties north and south of IH-10 along SH 146, including public and private facilities and services with less impact to the flow of traffic than currently occurs. Improving the traffic flow means a reduction in Nox in the area. No displacements would occur with this project.
Impacts on Natural and Cultural Resources
There are no floodplains or wetlands present within the project limits. There are also no cultural resources present. However, 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.
H-GAC will work with sponsor after emissions reductions calculation template is developed.
