 Shorty past I-691, Route 10 passes to the west of a park-and-ride lot, prior to coming to an oblique junction with Route 322, with a bridge over that highway; access from northbound Route 10 to eastbound Route 322 and from westbound Route 322 to southbound Route 10 is via Old Turnpike Road.At this junction, the route comes into both the town of Southington and Hartford County as Cheshire Road, and shortly afterward becomes Norton Street in the Milldale neighborhood.Route 10 crosses the Quinnipiac River, and passes east of another park and ride lot, to the south of its intersection with connector ramps to and from the eastbound direction of the I-84 freeway, before becoming the southern leg of the Main Street of Southington.
