toward Petersburg as Jefferson Davis Highway and north toward their James River crossing as Cowardin Street. US 360 passes the Art Works artist colony before passing over Norfolk Southern crossing the James River on the Mayo Bridge, which crosses Mayo Island in the middle of the river. US 360 reaches the north side of the river just west of the Triple Crossing; the highway passes under the east–west viaduct of CSX's Rivanna Subdivision and has a grade crossing of Norfolk Southern's Richmond District. The U.S. Highway passes under SR 195 (Downtown Expressway) follows 14th Street into the Shockoe Bottom neighborhood, where US 360 turns east onto Main Street, which carries US 60 and the GRTC Pulse bus rapid transit line. The two highways pass under I-95 (Richmond–Petersburg Turnpike) and CSX's Bellwood Subdivision and by the Main Street Station serving Amtrak's Northeast Regional trains during their four-block concurrency. Richmond to Reedville US 360 turns northeast onto 18th Street at Mason's Hall to pass along the west edge of the Church Hill neighborhood. At Grace Street, the highway splits into a one-way pair; westbound US 360 follows 17th Street. The U.S. Highway meets the eastern end of US 250 (Broad Street), then curves north and passes under the Leigh Street Viaduct, which carries SR 33. The two directions of US 360 come together one block before the highway turns east onto Fairfield Way. The U.S. Highway turns north onto four-lane undivided Mechanicsville Turnpike and has a partial cloverleaf interchange with I-64 before exiting the city of Richmond as a six-lane divided highway. US 360 passes through the Henrico County community of East Highland Park, where the highway intersects Laburnum Avenue, which leads to Richmond Raceway. The U.S. Highway crosses the Chickahominy River into Hanover County, where the highway reduces to four lanes at the southern end of Mechanicsville's US 360 Business. While on the Mechanicsville Bypass, US 360 has a diamond interchange with SR 156 (Cold Harbor Road). The movement from westbound US 360 to SR 156 is provided at the northern end of the bypass, which occurs a short distance south of US 360's cloverleaf interchange with I-295. Northeast of I-295, US 360 gradually transitions from suburban to rural surroundings. The transition is complete by the time the U.S. Highway crosses the Pamunkey River into King William County, where the highway's name changes to Richmond–Tappahannock Highway. US 360 passes through Manquin
