HOUSTON, Texas (KTRK) — Your drive into downtown Houston on the weekends will be a little easier this summer if you're coming from The Woodlands. The Metropolitan Transit Authority of Harris County will open the I-45 north freeway high-occupancy vehicle/high-occupancy toll express lanes to inbound traffic on Saturdays and Sundays starting in May. The move is meant to ease congestion for those of you headed to Astros games, a show in the Theatre District or any downtown activities. The summer program, providing free trips on the I-45 north freeway HOV lane, begins May 4 and lasts through July 28. Each Saturday and Sunday, the I-45 HOV lane will be open, inbound only, from 10 a.m.-7 p.m. each weekend day. There is no minimum occupancy required. However, towed trailers and trucks over one ton are not allowed.
