1.0 – 1.25

Travel Time Index (TTI) is a ratio that compares peak period travel times along a corridor to average travel times, thus estimating a relative level of rush hour congestion. Current TTI for the project area is between1.00-1.25, indicating that it takes 1.00 to 1.25 times as long to travel this corridor in the peak period than average, which is mildly congested. An at-grade crossing with UPRR causes congestion as the traffic is unable to cross while a train is moving through. Heavy traffic during the AM/PM peak hours with commuters.

The project will be reconstructing while also constructing Safety(install pavement markings) and operational improvements (grade separation) . The segment will be brought up to TxDOT and FHWA safety design standards. The proposed design would include edge line rumble strips or profile pavement markings.

US 90 provides access to SH 99 and SH 321 (a designated hurricane evac route). US 90 is an alternate route to take from Houston to the north during hurricane evacuations

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 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.

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.

Reducing traffic along at-grade crossing will help extend the service life of other facilities such as Stilson and SH 321. The pavement improvements will be built to design standard based on latest traffic data and the new interchange will have a service life of decades.

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 RR Gate or stop sign at this at-grade crossing.

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 grade separation with UPRR, the proposed project should reduce traffic congestion and help minimize travel delays on existing US 90 in and around the city of Dayton. The reduced congestion on US 90 should improve connectivity to and from the numerous employment opportunities along this corridor in Dayton. The reduced 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.
