Galveston County’s major thoroughfares and their Annual Average Daily Traffic (AADT)
Interstate 45 (Annual Average Daily Traffic = 80,300/ Peak = 149,000) (I-45 Traffic cams)
I-45 acts as the major transportation thoroughfare for Galveston County as it stretches from its northern to southern borders, ending on Galveston Island. Average traffic counts on I-45’s northern segments nearly double as it reaches League City and its rapidly expanding commercial industry. Its northern segment is highly commercialized sitting close to NASA facilities. As you travel south, properties become much more industrialized as you move towards the Gulf Intracoastal Waterway. Much of the land sitting on the coast is still rural, marked for prime future industrial development.
State Highway 3 (Annual Average Daily Traffic = 11,200/ Peak = 20,900)
SH 3 diverts from I-45 near the coast and runs close to the Texas City Industrial Complex. It continues to run parallel of I-45 where it eventually ends in southeast Houston near William P. Hobby Airport. SH 3 provides alternative travel to I-45 while allowing for direct access to major economic hubs such as the Texas City Port, Johnson Space Center, and the Hobby Airport. The highway is also integral to future construction plans as it will eventually bi-sect the site of SH 99’s continuation.
State Highway 6 (Annual Average Daily Traffic = 13,600/ Peak = 21,800)
State Highway 6 is known historically as the Old Galveston Highway as it stretches from the Texas-Oklahoma border to the border of Galveston. Locally, SH 6 diverts from I-45 near the coastline and runs northwest to southeast through Hitchcock and Santa Fe, up through I-10 and West Houston. This highway travels through the blue-collar communities of Galveston County along some of its last stretches of untamed land. Much of this area is primed for all forms of real estate development, including commercial, industrial, retail, and residential.
State Highway 146 (Annual Average Daily Traffic = 23,600/ Peak = 37,700)
SH 146 connects Texas City to Kemah as it directs through unincorporated segments of the County. It acts as a major transportation route for the Port of Texas City, the Texas City Industrial Complex and the Port of Houston. SH 146 also acts a major corridor of travel for tourists and vacationers to the Kemah Boardwalk with access to Texas’ Yacht Capital in Clear Lake Shores. The highway will soon be expanding from four to six lanes as it grows to accommodate the ever-increasing traffic requirements. Much of the land on the western portion of the highway is primed for industrial or commercial development with close proximity to the bay.
State Highway 275 (Annual Average Daily Traffic = 12,000/ Peak = 13,100)
SH 275 forks East from I-45 as it crosses the island and runs along its northern border to SH 87. This highway is integral in that it allows for major traffic to and from the Port of Galveston. This includes transportation of cargo as well as travelers embarking/disembarking from the nation’s fourth-largest cruise ship terminal. Along this highway, you will find a number of industrial sites, as well as the world-renowned UTMB campus.
Farm to Market 518 (Annual Average Daily Traffic = 20,700/ Peak = 32,600)
FM 518 runs over 25 miles long from Kemah to the western border of the county, ending in Brazoria County’s city of Pearland. This FM operates as an alternative logistical route for Brazoria County to easily reach either the Port of Houston or the Port of Texas City without the use of a Highway until reaching SH 146 near the coastline. As FM 518 runs through League City, the FM road becomes East and West Main St. in conjunction with I-45. Along this stretch, you can find League City’s historic district and much of the city’s commercial and retail storefronts outside of I-45.
Farm to Market 1764 (Annual Average Daily Traffic = 28,300/ Peak = 45,800)
FM 1764 leads from the heart of Santa Fe to Texas City where it acts as the main thoroughfare for commerce and retail. The road provides access throughout the area to residents traveling from east and west to the College of the Mainland. Along FM 1764 you can find office, residential, and commercial space available as the region beings to expand outward from I-45.
Farm to Market 2004 (Annual Average Daily Traffic = 12,600/ Peak = 15,000)
FM 2004 connects Galveston County to Port Freeport, giving the city of Hitchcock proximity to three separate port systems. As such, FM 2004 is quickly developing into an industrial complex and warehousing destination. Along FM 2004 in Hitchcock, you will find one of the region’s only free trade zones in partnership with the Port of Houston. This farm-to-market also provides direct access to Interstate 45 as it passes through the city of La Marque, directing underneath the interstate and into Texas City. Soon, construction will take place to widen FM 2004 by an additional two lanes, providing greater benefit to businesses and transportation services.
