State Route 14 Temporary (SR 14T) is a 2.73-mile-long[1] bypass around the city of Salem. SR 14T, a four-lane highway, begins at SR 14, Cleveland – East Liverpool Road, in Mahoning County. SR 14T crosses into Columbiana County and passes under County Route 61 and Goshen Road. SR 14T then has a diamond interchange with US 62 and SR 45. Exit ramps provide access from SR 14T to US 62 west and SR 45 south, and the two highways merge onto the SR 14T right-of-way as it continues past its terminus.
Although the SR 14T designation is unsigned, signs on the road read "TO US 62 / SR 45". The entire route is built to freeway standards with a speed limit of 65mph.
