Texas State Highway 150

State Highway 150 (SH 150) is an east–west highway in southeastern Texas beginning in New Waverly, starting at Interstate 45 and proceeds east going through Coldspring, where it turns southeast to Shepherd and terminates at Future Interstate 69/US 59.

SH 150 begins at an intersection with Interstate 45/FM 1374 just outside the city limits of New Waverly. The highway then enters New Waverly and intersects SH 75, with the two highways sharing a brief overlap, with SH 150 leaving SH 75 and turning east onto Gibbs Street near the town square, running concurrent with FM 1375 from SH 75 to Elmore Street. The highway leaves New Waverly near the intersection with Rogers Road. SH 150 travels through wooded areas and farmland of the Sam Houston National Forest and serves the unincorporated town of Old Waverly before reaching Coldspring near the southwestern shore of Lake Livingston.

The highway enters Coldspring at an intersection with FM 2025, where SH 150 also turns to the northeast, then turns east at SH 156 before turning south-southeast at FM 1514 in the town square. Leaving Coldspring, SH 150 turns in a more southeastern direction and continues to run through the Sam Houston National Forest. The highway turns back into a more eastern direction at FM 2666 then enters the town of Shepherd. In Shepherd, SH 150 is known locally as Main Street and intersects FM 222 and Loop 424 before ending at the southbound frontage road for US 59 (future Interstate 69).

SH 150 was designated on March 19, 1930 from US 75 (now SH 75) near New Waverly to Shepherd, replacing SH 45A and part of a branch of SH 45. On October 26, 1962, SH 150 was extended from US 75 to I-45.
