US 59 at SH 6 Triple Left-Turn Lane System

A triple left-turn lane system was constructed at the interchange of US Highway 59 (US 59) at State Highway 6 (SH 6) in the City of Sugar Land, Texas in November 2009. The system consists of an overhead dynamic message sign and in-pavement lights on the US 59 southbound frontage road approach to the interchange. The dynamic message sign displays two left-turn arrows and a shared left-through arrow alternating with “STAY IN YOUR LANE” message at approximately 800 feet from the intersection. The in-pavement lights delineate the three left-turn lanes through the intersection with two sets of lights following the pavement markings. This project was needed due to the high traffic demand of the south-to-east movement from Houston to Sugar Land and Missouri City. This diamond interchange has six and seven-lane approaches on the US 59 frontage roads and five-lane approaches on SH 6.
