Route 4 is an east–west primary state highway connecting rural Litchfield County to the Greater Hartford area of the U.S. state of Connecticut. It runs 46.72 miles (75.19 km) from the town of Sharon to the town of West Hartford.
Route 4 begins at the junction of Route 41 and Route 343 in Sharon as a rural, minor arterial road. In Cornwall, it briefly overlaps with US 7 to cross the Housatonic River on the Cornwall Bridge. Farther east in Cornwall, it intersects with Routes 125, 43, and 128 before crossing into Goshen. In Goshen, it meets Route 63 at a roundabout in the center of town. After entering Torrington, the road becomes more of a principal arterial road upon meeting the southern end of Route 272. After skirting the northern edge of downtown, it meets the Route 8 freeway at Exit 44, and briefly overlaps with US 202 just east of the interchange. The road turns southeast and returns to more of a rural character, meeting the southern end of Route 183 before entering Harwinton, where it turns easterly at the junction with the eastern end of Route 118. Shortly thereafter, it meets the western end of Route 72. In Burlington, it meets the northern end of Route 69 in the center of town, and descends into the Farmington River valley before meeting the southern end of Route 179. After turning southeast, it follows the Farmington River and enters the town of Farmington, where it crosses the river just before entering the village of Unionville. From here to its eastern end, it becomes a suburban primary arterial road known as Farmington Avenue. In the center of Unionville, Route 4 intersects Route 177, and it intersects the southern end of Route 167 on the east end of the village. After crossing the Farmington River once again, it intersects Route 10 in the center of town. It then meets SR 508, which provides access to I-84, while Route 4 eastbound traffic continues through one of the state's few jughandles. After passing the University of Connecticut Health Center, it enters West Hartford. State maintenance continues for another 0.9 miles (1.4 km) to the intersection of Boulevard, where Route 4 ends and Farmington Avenue continues as a local road through West Hartford Center and into Hartford, ending at an intersection with Asylum Avenue just west of Union Station and I-84 Exit 48/48A.
