Southbound lanes of the Thruway near exit 10 (Nyack – South Nyack – US Route 9W) will shift slightly on Monday, Nov. 17 to allow for construction of a temporary all-electronic toll collection (AETC) gantry. Crews will construct and test the AETC system over the next six months in preparation for the eventual removal and reconstruction of the Westchester toll plaza. The permanent AETC toll gantry will be located in Tarrytown near the site of the existing toll plaza.
