Spur 342 is a state highway spur route located completely within the city of Galveston, Texas. Officially named Butterowe Boulevard, but mostly known by locals as 61st Street, it stretches 2miles across Galveston Island.
Spur 342 begins at an intersection with Seawall Boulevard on the Galveston Seawall in Galveston, Galveston County, heading north-northwest on 61st Street, a six-lane divided highway. From here, FM 3005 heads west on Seawall Boulevard. Spur 342 heads through commercial resort areas with some residences. After passing more businesses, the highway crosses Offats Bayou.[1] A short distance later, Spur 342 comes to its northern terminus at an interchange with I-45 in a commercial area.[2]
Spur 342 was designated onto its current alignment on September 26, 1960. It has remained there since.
