Project Narrative

The Port of Texas City is a growing petrochemical and industrial port. Current truck access to LP 197 from I-45 requires stopping at two intersections plus a double tracked railroad crossing. Additionally, there is a short weaving area that trucks must maneuver through in order to access LP 197 from the existing interchange. The focal points regarding the need for this project are as follows: • Inefficient transitioning of traffic at the existing IH 45/LP 197 interchange; interchange is currently below current design standards • Traffic congestion and delays due to the at-grade railroad crossing near intersection of LP 197 and SH 146 • Future truck traffic resulting from the development of the Shoal Point Terminal Facility • Current intersection of IH 45/LP 197 is located within the 100-year floodplain The existing interchange does not provide a direct connection between IH 45 and LP 197. Currently, commuters traveling along IH 45 must take the SH 146 exit and travel a short distance along SH 146 before reaching a three-way stop. From this stoplight, commuters can turn right onto LP 197 or continue northward onto SH 146 or SH 3. Atypical curves at this three-way intersection and the IH 45/LP 197 interchange are currently below design standards and do not allow for efficient transitioning, thus increasing the potential for traffic delays. The traffic volume at the intersection of LP 197 and IH 45 is expected to increase by almost 25%, which could contribute to increased inefficiencies without the proposed improvements. The proposed design would eliminate the three-way intersection and provide an interchange that meets current standard design criteria and functions more efficiently and safely. An at-grade railroad crossing currently traverses LP 197 north of the intersection of LP 197 and SH 146. This creates traffic congestion and delays when a train crosses the area and the intersection is blocked. The proposed direct connectors will be elevated over this at-grade railroad crossing, allowing commuters to avoid the crossing and reducing traffic delays. The City of Texas City is constructing a new container terminal northeast of the proposed project. Over 10,000 daily truck trips are expected to be generated in 2025 by the proposed container terminal. The proposed project will provide access from the terminal to LP 197 at the FM 519 intersection. The proposed direct connectors will create an alternative route, providing a more efficient travel route for the increased truck traffic travelling to IH 45 The November 2002 EIS prepared for the Shoal Point terminal project concluded that increased roadway cargo traffic volume would create an unacceptable LOS, or LOS F, at the SH 3 and LP 197 intersection. After construction of the proposed project direct connectors, an LOS of D would be achieved. The project would provide direct access from I-45 to LP 197. It would eliminate the at-grade intersections and at-grade railroad crossings trucks currently have to navigate. The project would upgrade the design standards and improve safety by providing a modern connection to the port. The purpose of the proposed project includes the following: • To improve existing and future congestion of predicted traffic by constructing continuous non-stop connector ramps from IH 45 to LP 197, and to improve inefficient geometry of the existing IH 45/LP 197 interchange by meeting current design standards • To avoid congestion and delays at the at-grade railroad crossing near the intersection of LP 197 and SH 146 • To provide alternate routes for the increased truck traffic created by the Shoal Point Terminal Facility • To provide an alternate connecting route between IH 45 and LP 197, which is not subject to flooding The existing intersection of IH 45/LP 197 is located within the 100-year floodplain and currently experiences flooding during heavy rainfall periods. This creates traffic congestion and safety concerns. The elevated interchange would not be subject to 100-year flooding and would improve safety and mobility. The proposed project would construct two direct connectors from southbound I-45 to LP 197 and from LP 197 to northbound I-45. The direct connectors would be on new location as bridge structures that span existing roadways and railroads. Various direct connector alternatives and alignments for I-45 and LP 197 were analyzed. Direct connector projects could be phased one at a time.

Narrative Benefits

The project would increase safety by constructing connectors that bypass existing at-grade intersections and railroads. The project would provide a dedicated route for truck traffic destined to or from the Port of Texas City. The existing intersection of IH 45/LP 197 is located within the 100-year floodplain and currently experiences flooding during heavy rainfall periods. This creates traffic congestion and safety concerns. The elevated interchange would not be subject to the 100-year flood and would improve safety and mobility.

The project would improve mobility for truck traffic in the Texas City area by providing direct connectors to I-45. It would also eliminate the at-grade railroad crossing.

The improvements are needed to enable the roadways to continue to carry the increasing level of traffic. The current facility is below current design standards, and lies within the 100-year floodplain. Water standing on the roadway contributes to pavement degeneration. The elevated interchange would not be subject to the 100-year flood and would improve safety and mobility.

The project would connect a regionally significant interstate highway to a major seaport. The location is currently a freight bottleneck, and improvements would ease the transport of goods through the region.

The project would reduce delay for truck traffic by providing a higher speed facility without the multiple existing stop conditions. This would reduce adverse impacts on air quality in our nonattainment area.
