State Route 142 marker

State Route 142 (SR 142) is a state highway in Madison County, Ohio, west of the state capital Columbus. It begins in downtown London and acts as a spur of U.S. Route 42 serving West Jefferson, before ending at an interchange with Interstate 70 north of West Jefferson. The interchange provides Interstate access to West Jefferson, nearby Lake Darby, and Plain City via Madison County Route 7.

The route begins at the intersection of Main and High streets in downtown London. Main Street carries SR 56 both southeast and northwest of here, SR 38 and SR 665 to the southeast. High Street carries US 42 southwest and northeast of this point and SR 38 northeast of there. US 42, SR 38, and SR 142 form a concurrency and head northeast along High Street for three blocks. At Elm Street, US 42 and SR 38 break off from High Street leaving SR 142 along to continue northeast along High Street. The route passes through residential neighborhoods at first but near the eastern outskirts of the city, SR 142 passes several large distribution warehouses. For the five miles (8.0 km) between London and West Jefferson, the route passes many farms and some houses. As the route enters the village limits of West Jefferson, SR 142 and a Norfolk Southern railroad line head northeast into the village and gradually come closer together. Residences and local roads line the north side of the route. At US 40, officially Main Street but also a part of the National Road, SR 142 and US 40 intersect at a skewed angle. Both routes head under the aforementioned rail line and into the central business district of the village. The two routes exit the central portion of the village and enter Jefferson Township. At Plain City-Georgesville Road (CR 7), SR 142 turns north and heads into an outer reach of West Jefferson. The north-south portion of the route is surrounded mostly by farmland but a satellite office of the Battelle Memorial Institute is located along this portion of SR 142. The route ends at I-70's exit 85, a diamond interchange. CR 7 continues north towards Plain City.
