TheYokohane Route (横羽線,Yokohane-sen), signed asRoute K1, is one of the tolled routes of theShuto Expressway system serving theGreater Tokyo Area and is one of seven of the routes in the system servingKanagawa Prefecture. The route is a 19.7-kilometer (12.2 mi) long radial highway running southwest from the southern terminus of theHaneda Route inŌta nearHaneda International Airport inTokyo to theKariba Route inNaka-ku, Yokohama in Kanagawa Prefecture. Alongside the Haneda Route, it connects Tokyo'sInner Circular Route in central Tokyo toYokohama.

Route K1 begins at the Haneda interchange in Ōta as a continuation south for theHaneda Route into Kanagawa Prefecture. From this northern terminus, it travels southwest out of Tokyo, crossing in to the eastern part of the city ofKawasaki in Kanagawa Prefecture. The largest junction along the Yokohane Route in Kawasaki is at Daishi Junction where the highway meets theKawasaki Route at its western terminus. In Yokohama, the expressway intersects theYokohama North Route, theDaikoku Route,National Route 15, theMitsuzawa Route, andNational Route 1. Route K1 meets its southern terminus at Ishikawachō Junction with the Kariba Route.^[1]

The speed limit along almost the entire length of the Yokohane Route is set at 60 km/h. The only exception is at the southern terminus of the route between Yokohama-kōen and Ishikawachō Junction where the limit is lowered to 50 km/h.^[2]

The first section of the Yokohane Route was opened to traffic on 19 July 1968 between the interchanges at Asada and Higashikanagawa. Later that year, on 28 November, the expressway was extended north to its current northern terminus at Haneda. Next it was extended south to Kinkō Junction on 7 August 1972. It was extended further to the south, terminating at an interchange at Yokohama-kōen on 7 March 1978. The Yokohane Route was completed upon completion of its extension south to its southern terminus at Ishikawachō Junction on 2 February 1984.^[3] Work began in 2015 to replace the Daichi Bridge that carries that expressway over theTama River after fatigue cracks were found throughout the old bridge. The replacement project is set to be completed in 2023.^[4]
