Existing US 90 through Dayton has an AADT of over 22,000 on a 4-lane facility with multiple signalized intersections. This facility is severely congestion at peak times during the day. The proposed relief route bypasses downtown Dayton, reducing congestion, allowing for trucks to travel more freely. Grade separations at major cross roads and the UPRR will be provided.

The proposed project would tie into SH 146, FM 563, and US 90 east, which are all evacuation routes. The Dayton relief route would connect these designated evacuation routes.
Other Investment Category Focused Criteria
Existing US 90 through Dayton has an AADT of over 22,000 on a 4-lane facility with multiple signalized intersections. This facility is severely congestion at peak times during the day. The proposed relief route bypasses downtown Dayton, reducing congestion, allowing for trucks to travel more freely. Grade separations at major cross roads and the UPRR will be provided. The relief route will add capacity to the overall east-west movement through the area.
The Dayton area continues to grow, with industrial and residential developments currently planned on the west side of town. The proposed relief route provides an alternate route for those wanting to bypass downtown Dayton and avoid the numerous signalized intersections. The relief route will add capacity to the overall east-west movement through the area.
The proposed relief route would reduce congestion and traffic volume on US 90 and thus should improve safety for bike/pedestrian users of that facility.
The proposed relief route should help reduce the traffic volume on existing US 90 through Dayton. This should likewise reduce congestion and improve the level-of-service for all users of the existing roadway (including transit providers).
This project creates an alternate route for US 90 in the event of damage to existing infrastructure through Dayton or if US 90 is partially or completely closed due to a vehicular accident. Also, by allowing through-vehicles to by-pass downtown Dayton, the resulting reduced congestion should provide emergency vehicles better access through Dayton.
By reducing traffic on existing US 90, the proposed project should help extend the service life of the US 90 pavement. The pavement section for the proposed relief route would be built to design standard based on the latest traffic data and the new roadway would have a service life of several decades with minimal maintenance needed.

The proposed relief route would remove conflict locations as it will have grade separations at RR and cross streets. It would reduce traffic volume along the existing corridor from through vehicles, including heavy truck traffic, again eliminating many potential conflicts. The proposed relief route would be built to current design standards with 12' travel lanes and 10' outside shoulders, and the proposed design should include edge line and centerline rumble strips.
Resiliency
Low
High
The relief route 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. With the relief route being designed to potentially higher drainage standards than the existing roadway (US 90) the risk of interruption of traffic due to flooding should be minimized. The profile of this new location roadway would be set at a sufficient elevation to not be overtopped by the design flood and this route could be used as an alternative to US 90 if there were flooding on US 90.

By providing an alternate route around Dayton, the proposed project should reduce traffic congestion and help minimize travel delays on exisitng US 90 through Dayton. The reduced congestion on US 90 should improve connectivity to and from the numerous employment opportunities along this corridor in Dayton. The reduced traffic volume and congestion on US 90 should also improve safety for bike/pedestrian users of that facility and it should reduce trip time for transit users (area served by Brazos Transit).
The footprint of the proposed roadway improvements would be minimized to limit impacts to adjacent properties, thus reducing any possible displacements of persons, businesses, etc. Any sound walls that are identified prior/during the National Environmental Policy Act (NEPA) process will be constructed on this project. Construction of this relief route would lessen traffic on existing US 90 and would improve the level of service of US 90 (improving access to adjacent properties and improving connectivity along US 90).
Impacts on Natural and Cultural Resources
Floodplains present in the project vicinity include the 100 year, 500 year, and a floodway. In addition, 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 floodplains present, the project would be designed to have no negative impact to the floodplain and we would coordinate with the floodplain administrator concerning these.
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.
H-GAC will work with sponsor after emissions reductions calculation template is developed.
