Transportation in Sugar Land, Texas includes multiple highways and an airport. There is no mass transit system, but it has been a possible candidate for expansion of Houston's METRORail system by means of a planned commuter rail. Since many of Sugar Land's residents work in Houston, thus creating routine rush hour traffic along the city's main thoroughfare, Interstate 69/U.S. Highway 59, there has been large support in the area for such a project (However, the city is not within Metro's service area). Major thoroughfares Interstate 69/U.S. Highway 59, the major freeway running diagonally through the city, has undergone a major widening project in recent years to accommodate Sugar Land's daily commuters. The finished portion of the freeway east of State Highway 6 has eight main lanes with two diamond lanes and six continuous frontage road lanes. Interstate 69/U.S. Highway 59 has been widened to just west of State Highway 6 out to State Highway 99. U.S. Highway 90A, a major highway running through Sugar Land from west to east and traverses through a historic area of the city, known as "Old Sugar Land".

State Highway 6 is a major highway running from north to southeast Sugar Land and traverses through the 10,000 acre (40 km2) master-planned community of First Colony. Construction is about to start on a bridge over University Blvd and U.S. Highway 90A from First Colony Blvd to north of the railroad track at U.S. Highway 90A. When completed, it will have six main lanes and frontage roads. Grand Parkway/State Highway 99 is a new highway that opened in 1994 with frontage roads. The main toll lanes opened in 2014.
