Investment Category-Focused Criteria
Roadway
Principal Arterial or Higher Functional Class
The proposed grade-separation will add another north-south connector across UPRR, helping to provide alternate routes in case of inoperability along the existing roadway. The grade separation will also provide emergency vehicles an option of crossing over UPRR without being impacted by a crossing train.
The proposed project would tie into US 90 which connects to SH 321 and FM 1960 (tying into SH99), which are all evacuation routes or alternate routes. The US 90 Interchange would improve connectivity to these designated evacuation routes.

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 congested at peak times during the day and includes additional delays from the at-grade railroad crossing. The proposed grade separation provides better access between FM 1960 and US 90, removing the conflict of an at-grade crossing. This will improvement mobility and reduce congestion by removing the at-grade crossing with future traffic diverting onto the new crossing instead of travelling through Dayton to access FM 1960. Truck traffic will have a better access point from FM 1960 to US 90 with the grade separation.
BMT is currently working with UPRR at the nearby wye crossing that will close the at-grade access/crossing from FM 605 & Waco St to US 90 at the Waco St. intersection. There is not another UPRR crossing that connects the roadways north of US 90 , therefore the grade separated crossing at Klemp St is needed.
The proposed project improves traffic operations through reducing congestion on the US 90 roadway by adding a grade separation across UPRR. The grade separation will remove conflict with the existing train tracks and provide an alternative route to and from FM 1960 rather than the current route at Waco St. where there is an at-grade UPRR crossing. This will allow for more free flow on US 90 from commuter traffic.
The proposed interchange will remove traffic from other crossings closer into town and improve bike/ped safety by reducing traffic on those other facilities.
The proposed interchange will remove traffic from existing at-grade crossings, which would likewise reduce congestion and improve LOS for all users of the facility, including transit services.
Planning Factors Criteria
1. What is the existing fatality crash rate at the project location? Regional crash data is available online on the crash data viewer. H-GAC staff will provide assistance in calculating the crash rates upon request.

The proposed interchange will create a grade-separation over the UPRR. This will reduce conflict from an at-grade crossing and allow for improved traffic operations. Based on crash data the serious injuries occurred at the nearby RR Gate or stop sign at the at-grade crossing.

Low
The proposed project 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. Specific improvements may include additional cross drainage capacity and possibly raising the proposed roadway profile if determined necessary by the hydraulic analysis.

By providing a grade separation across the UPRR line, the proposed project should reduce traffic congestion and help minimize travel delays on existing US 90. The reduced congestion 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 help prevent impacts to adjacent properties. The addition of a grade separation with the UPRR will still maintain access to adjacent properties including public and private facilities and services with less impact to the flow of traffic than currently occurs.
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.
