插件说明: These Lots are designed to provide thru-traffic for all VEHICLES. Filtering vents in each corner manipulate the exhaust released from heavy traffic, purifying the surrounding air. This set includes a 2x1 & 3x1 ROAD Filtering Tunnel as well as a 2x1 & 3x1 ONE-WAy Filtering Tunnel. The LOTs icons are located under Transportation Tools>Miscellaneous Transit in-game.
