Route 190 is a state route in the northern part of the U.S. state of Connecticut. It starts at Route 75 in the town of Suffield and proceeds eastward across the Connecticut River through the towns of Enfield, Somers, and Stafford. It ends at Route 171, in the town of Union. Route 190 was established in 1932 as a route between the state line at Southwick and the town of Enfield. The route was later extended eastward to Union but was truncated in the west to Suffield center. The segment of Route 190 in Suffield, from Route 75 to Route 159, is also known as the "Corporal Stephen R. Bixler Memorial Highway", named for a Suffield native who died in the Iraq War. Route 190 starts as Mapleton Avenue. The road then bears right onto Thompsonville Road to connect to Route 159 (East Street). After travelling south on Route 159 for 0.6 miles (0.97 km), it turns eastward again on Hazard Avenue, crossing the Connecticut River from Suffield into Enfield on the Enfield-Suffield Veterans Bridge.
