Florida State Road 136
State Road 136 (SR 136), locally known as Thunder Road, is a 3.396-mile-long (5.465 km) east–west route in Suwannee, Columbia and Hamilton Counties. Its western terminus is just west of Interstate 75 and is a continuation of County Road 136 in rural Suwannee County. Its eastern terminus is US 41 in White Springs.
For the most part, SR 136 serves as an access road from Interstate 75 to White Springs. The State Road designation begins 0.061 miles (0.098 km) west of I-75, where County Road 136 ends. The road then enters Columbia County, travelling about 3 miles (4.8 km) before crossing the Suwannee River into Hamilton County. Upon entering Haminton County (and the city of White Springs), the road is renamed Bridge Street. The State Road designation terminates at US 41 (SR 25), but Bridge Street continues north as a local road.
