State Route 237 (SR 237, now Best Road, Farm to Market Road, Mactaggart Avenue and West Bow Hill Road) was a 9.07-mile (14.60 km) Washington state highway that ran from SR 20 in Fredonia, through Edison and ending at SR 11 east of Edison. The roadway was established in 1937 as Secondary State Highway 1C and was renumbered to State Route 537 in 1964, before being renumbered to SR 237 in 1975. The road was decommissioned in 1991.
State Route 237 (SR 237) began at an intersection with SR 20 as Best Road. From the terminus, the roadway turned north and crossed railroad tracks that are owned by the BNSF Railway and became Farm to Market Road. Once over the tracks, the highway passed the Skagit Regional Airport and intersected Josh Wilson Road, which travels west to Bay View. SR 237 traveled over the Samish River and later entered Edison where it curved east as Mactaggart Avenue. The highway bridged Edison Slough and became West Bow Hill Road to continue east across the Edison Slough again and end at an intersection with SR 11. In 1970, the intersection with SR 11 had a daily average of 1,410 motorists, making it the most used section of the roadway as a whole. In 1991, the busiest section moved south, before the intersection with Ovenell Road, the southern connector to Skagit Regional Airport, with a daily average of 2,300 motorists.
