In the announcement Monday, TxDOT explained the closure of the SH 146 westbound connector ramp to I-45 southbound, which will lead to necessary work as part of a robust reconfiguration project,\u00a0will now occur Aug. 7. The closure was originally scheduled to take place July 31.<\/p>\n
The closure is part of a $226 million I-45 expansion project being undertaken by TxDOT\u00a0between FM 519 in La Marque down to the Texas City Wye, the Y-shaped interchange facilitating traffic both getting on and coming off I-45 northbound from SH 146. In late 2025, TxDOT public information officer Danny Perez told the Galveston Daily News<\/a> he expected the work at that stretch of SH 146, which will reconfigure the Wye into a diamond interchange,\u00a0to be completed by summer 2028.<\/p>\n But that just scratches the surface of work happening on and around I-45 in the Galveston area. Other work includes widening the causeway bridge as a way “to reduce roadway flooding, improve mobility and congestion and improve hurricane evacuation,”\u00a0per TxDOT<\/a>. In all, TxDOT has about $725 million invested in this area of the region, per the Daily News.<\/p>\n
