In the 1930s, the Worcester Turnpike was paved as Massachusetts Route 9, an intercity highway, which forced the removal of streetcars. Buses replaced Boston and Worcester Street Railway cars on June 11, 1932. That November, paving reached Chestnut Hill; Huntington Avenue cars were cut back to Cypress Street and Ipswich Street cars to Brookline Village, and a Chestnut Hill–Brookline Village bus route was added. The Ipswich Street line was cut to a short shuttle route in mid-1933, with a new Brookline Village– bus route. Cypress Street Carhouse closed on December 3, 1933; the Cypress Street route joined the South Huntington Avenue route in operating from Arborway Yard.
