Project Need
The City of Sugar Land, Texas, has successfully implemented a Triple Left Turn Lane System at the intersection of US 59 and SH 6. This project addresses heavy left turn movements, enhances signal spacing, and improves freeway ramp operations. The total project cost was $325,000, significantly less than modifying the US 59 overpass. The installation, which includes a dynamic message sign system, has been well received by the public with no complaints. The project was approved under MUTCD for crosswalks and features innovative lane delineation technology.
