The Grand Strand Area Transportation Study (GSATS) encourages citizens to get involved in the ongoing US 17 Corridor Study in Georgetown County.  The US 17 Corridor in Georgetown County currently carries an average of 35,000 vehicles per day.  This area has experienced significant growth which has led to increased congestion and safety concerns along the corridor.


There will be a public meeting to present the findings of the Draft US 17 Corridor Study in Georgetown County. The project study area covers the Waccamaw Neck Area of Georgetown County from the Waccamaw River bridge to the Horry County line. The project consultant, AECOM, has reviewed the existing conditions observed along the corridor and will present their findings during the meeting. The projected 2040 traffic conditions and the resulting transportation improvement recommendations that will help maintain US 17 as a safe and efficient corridor will also be reviewed during the presentation. There will be an opportunity for attendees to ask questions following the presentation.

To ensure the public health and safety of attendees during the COVID-19 pandemic this meeting will be held virtually via Zoom at the following link:
