IH 45 South Reconstruction Texas Department of Transportation 1/12/2015 5:43:13 PMProject Narrative
The need for the project is based on existing and anticipated congestion, safety, operations/state of good repair, and economic conditions of the area, including: • Demand exceeds capacity during both of the daily commute periods • Many of the critical IH 45 bridge crossings require replace or major reconstruction • Many section of IH 45 need major pavement maintenance • Improved operational efficiency and safety, • Correct roadway deficiencies, • Added capacity for project population and economic growth; • Improved mobility for hurricane evacuations due to IH 45’s designation as a hurricane evacuation route is a documented concern; • Roadway flooding contributes to reduced highway capacity and increased congestion • Current truck traffic is at seven percent and expected to increase; • Facility is considered a freight bottleneck; • Improved connectivity is needed for major employment generators such as Galveston Island, NASA communities, and the nearby ports. I-45 is a major north-south corridor that connects Houston and Galveston. It serves daily trips to/from employment centers and provides access to tourist attractions on Galveston Island. It is also the primary evacuation route for Galveston Island during hurricane events. The existing roadway is a 6-lane freeway (three mainlanes in each direction) with 2-lane frontage road lanes in each direction. The need for more efficient hurricane evacuation is a documented concern as is the need to reduce localized flooding during heavy rainfall events. The existing facility does not meet current design standards. In August 1999, TxDOT completed a Major Investment Study ("MIS") for the IH 45 South ("IH 45S") corridor, which extends from Beltway 8 in Houston to 61st Street in Galveston in order to define the scope and characteristics of the proposed transportation infrastructure investment. Three corridors were defined in this study. The north corridor is the segment of IH 45 from Beltway 8 to FM 518. The middle corridor is the segment of IH 45 beginning at FM 518 to the Texas City Wye, and the south corridor is the segment of IH 45 beginning at Texas City Wye to 61st Street in Galveston. Five goals of the MIS study were also developed that consisted of reducing traffic congestion, improving hurricane evacuation, improving safety, providing travel options, and protecting the natural and social environment. The purpose of this project is to support the goals of the Interstate system, which is to provide safe and efficient transportation for the movement of persons and goods. It is in the national interest to maintain the Interstate System and to provide the highest level of service in terms of mobility and safety and to maintain a quality driving surface. The purpose of the project is to reduce traffic congestion, improve mobility, correct design deficiencies, and reduce hurricane evacuation times, while protecting the human environment. The desired design benefits of the project include: Reduced congestion/improved mobility Reduce potential for flooding Improved travel options and improved access to alternative modes of transportation Avoid, minimize, mitigate potential environmental and community impacts The project would increase capacity to accommodate future growth in the area. It would improve evacuation capability of the corridor for the region during hurricane events and would reduce localized flooding to the extent practical. The project would also enhance safety by upgrading the facility to current design standards. The proposed project would widen the existing facility from a 6-lane to an 8-lane freeway, providing one additional mainlane in each direction. The project would also incorporate pedestrian and bicycle accommodations along the I-45 frontage roads. Alternatives for the I-45 widening were considered during the major investment study that was conducted for the corridor from Beltway 8 in Houston to 61st Street in Galveston. They included a No-Build Alternative, a Transportation Systems Management Alternative, and four Build Alternatives. See the attached Corridor map for staging of this IH 45 South Corridor. The project in this application is 2.5 miles long and opportunities for staged construction are limited.Project Narrative
Yes Environmental Assessment (EA) Please Select Yes USACE permit is required, and will be obtained by August 2019. 03/01/2015 No No Project is on the Interstate. Utility adjustments will be by provider with TxDOT reimbursement. No • A MIS was conducted for this corridor. The MIS team included representatives from TxDOT, HGAC, METRO, FHWA, FTA, TNRCC (TCEQ), as well as Harris and Galveston Counties. • • MIS Public Meeting - April 28, 29, and 30, 1998. These meetings gave the public the opportunity to provide input about transportation problems and needs within the IH 45 South Corridor. Public comments from this meeting helped the MIS team establish its corridor goals and objectives. • • MIS Public Meeting - September 15 and 16, 1998. Public input at these meetings was used to help in the development of six viable alternatives for improving the corridor. • • MIS Public Meeting - March 23 and 24, 1999. These meetings gave the public an opportunity to comment on the six viable alternatives, which emerged from the MIS. This public input was used to help to select the preferred alternative. • • Public Meeting for Schematic - TBD Most of the project can be accommodated within the existing right-of-way. Possible corner clips may be required at the intersections. No right-of-way has been acquired to date.0500-01-119 - Schematic - IH 45 S from 61st St to S of Causeway.pdf
