  • CH7 Bridges and Tunnels Pp340
    Bridges and Tunnels Fifty miles inland, on a flat plain drained by small bayous, Houston in its early days did not seem destined to become a city of bridges. There were no rivers to cross and no nearby bays or lakes to block the city’s growth. Although Houston was free of impediments, the addition of a man-made barrier would be the event that propelled Houston into the ranks of the nation’s largest cities. Dredging of the Houston Ship Channel to a depth of 25 feet (7.6 m) was completed in June 1914, and the channel was officially opened by President Woodrow Wilson on November 10 of that year. The rest, one might say, is history, as the ship channel spurred Houston’s industrial boom. The construction of one great work of infrastructure, the Houston Ship Channel, would ultimately necessitate other construction projects to bridge the man-made divide. Houston would not become a great bridge city on the order of New York City or San Francisco, but would still develop a nice collection of bridges and tunnels to complement its freeway system. In comparison to most cities in the United States, Houston’s major bridge crossings are a relatively modern development, with the first high-level bridge span opening in 1973. With newness comes better design and wider spans, but as this history shows, Houston’s bridges have all had their share of problems. The complete history of Houston’s bridges, however, predates the construction of the modern Houston Ship Channel. While Houston was still a mosquito-infested outpost on Buffalo Bayou, one of the nation’s more prosperous cities was thriving just 50 miles (80 km) to the south—on Galveston Island.

  • Michael A. Stafford Harris County Attorney
    Michael A. Stafford Harris County Attorney RECEIVED SEP 17 2002 OPINIONCOMMITTEE September 13,2002 Honorable John Comyn Attorney General of Texas Supreme Court Building P.O. Box 12548 Austin, Texas 78711-2548 Attention: Opinion Committee Re: Is Harris County authorized to participate in the design and construction of a proposed bridge wholly outside of Harris County from Galveston Island to Point Bolivar? Dear Sir: On June 5,200 1, the Harris County Commissioners Court approved a resolutionpooling several toll road projects. This resolution listed the proposed Galveston Island to Point Bolivar Bridge as one of the pooled projects. On December 13,2001, the Texas Department of Transportation (TxDOT) promulgated a minute order proposing that Harris County (the “County”), Galveston County, and the Federal Highway Administration participate with TxDOT in discussing various alternatives for a proposed toll bridge from Galveston Island to Bolivar Peninsula and possibly to develop an agreement outlining each agency’s participation. The TxDOT District Director has now proposed that the County enter into an agreement under which the County will acquire a preliminary engineering report for the project. 10 19 Congress, 15* Floor l Houston, TX 77002-l 700 l Phone: 7 13-755-S 101 l Fax: 713-755-8924 Honorable John Corny-n -2- September 13,2002 The Director of the Harris County Toll Road Authority has advised that the project would allow traffic to Galveston from the east to avoid Interstate 10 and Harris County, lessen the burden upon Harris County’s infrastructure, and contribute to air quality. The route could also serve as an additional hurricane evacuation route from the island, again relieving congestion.

  • Newsletter Vol 2 No 3.Pub
    Volume 2, Issue 3 Message from our President Fall 2008 The Texas Chapter of the ASBPA will be having the last quarterly meeting of 2008 in South Padre Island at the Shrimp Haus Restaurant at Schlitterbahn Beach Water- park on December 5. One of the topics of discussion will be the two devastating storms that have hit the Texas coast this year, Hurricanes Dolly and Ike. Both have done a significant amount of damage to the coastal communities. The most recent storm, Hurricane Ike, struck the upper coast with a vengeance. It was 1 mph shy of a Category 3 hurricane but it had a Category 4 storm surge. The upper coast was severely impacted by Hurricane Ike; the descriptions on T.V. and in the newspapers cannot give an accurate picture of the destruction and devastation to the areas. Rows of beachfront homes were lost as well as bay front communities. On the Bolivar Peninsula alone, 3600 homes were destroyed and gone forever. The Seawall on Galveston Island did its job in protecting the infrastructure, buildings, and homes behind it but the real damage to the famed old historic downtown area came from backside of the island in the form of rising bay waters that flooded sev- eral streets and buildings with 11 to 14 feet of water causing damage to 75% of the homes and businesses. The old Blue Water Highway from San Luis Pass to the City of Surfside in Brazoria County was literally washed away. Matagorda, Chambers, and Jefferson County were badly impacted as well. Favorite bird watching reefs no longer exist and sensitive ecosystems are being overrun by salt tolerant species.

  • Galveston Island Study
    Galveston Pedestrian and Bicyclist Special Districts Study September 2006 A L E O A D A L Y C O M P A N Y Executive Summary Introduction In 2004, H-GAC conducted a study to identify districts where there were high levels of existing or potential pedestrian and bicyclist activity, and where there were significant Legend opportunities to replace vehicle trips Major Streets with pedestrian or bicycle trips, and Minor Streets to improve pedestrian and bicyclist Þ Schools safety. Fifteen districts were Study Area identified throughout the region, "H ot Sp ot " with two of the top districts located on Galveston Island. H-GAC decided to treat these two districts together, and defined the Study Area as the urban portion of the island, from 1st to 53rd Streets, and from Harborside Drive to the Seawall. On the map at right, the circles represent the two districts, with the triangular shaded region representing the study area. The study area covers Galveston Island from 1st to 53rd Streets. Study Process The Project team used a charrette process to solicit input from the public, city, county and state representatives. Introductory meetings were held in May 2006 to explain the purpose of the plan and solicit general comments. The presentation included initial data such as traffic counts, locations of schools and other attractors, as well as the location and severity of motor vehicle crashes involving pedestrians and bicyclists. A second series of public input workshops were held in June. Workshop attendees were presented additional data, such as other planned and proposed projects under development within the project study area, as well as examples of best practices to accommodate pedestrians and bicyclists.
