Route 8 continues through the river valley on the east side of Mount Greylock and enters the town of Adams, where it meets the northern end of Route 116. Shortly after entering the city of North Adams, another Route 8A (officially Route 8A(U) splits east along Hodges Cross Road. In downtown North Adams, Route 8 crosses to the east of the South Branch of the Hoosic River, passes under Route 2 (Mohawk Trail) just south of the Massachusetts Museum of Contemporary Art, then curves east and then south along St. Anthony Drive and Holden Street, respectively, to intersect the other route. Routes 2 and 8 head east along a four-lane boulevard to Eagle Street, where the highways meet the northern end of Route 8A. The highways follow two-lane Mohawk Trail east across the North branch of the Hoosic River to Beaver Street, onto which Route 8 turns north. The highway follows the river north through the town of Clarksburg to the Vermont state line, where the road continues as VT 8 and VT 100.
