at Lake Ridge Road (Durham Regional Road 23), just west of Highway 412. A small portion of road parallel to Kingston Road is called Old Kingston Road running near the Highland Creek, east of Morningside Avenue. There is a discontinuity and a large reduction in capacity as the road reverts to the original route at an interchange with Military Trail, where traffic is defaulted onto Highway 2A, which was constructed in 1947 as a precursor to Highway 401, and later became a spur when that highway was extended westwards along a more northerly alignment. To facilitate traffic to and from Highway 401, and to preserve the historic village of West Hill, the spur was retained and Kingston Road was never widened and reconnected as a through street, despite having six lanes on either side of West Hill. Other former, parallel sections also called Old Kingston Road, exist in Ajax and Courtice, although Kingston Road proper does not reach Courtice today. There is also an old section of the old Danforth Road in Grafton. The southwesternmost section in the Beaches area is a traditional urban street with storefronts, high pedestrian traffic, and streetcars. The speed limit in that section is . Until Highway 401 was constructed, Kingston Road was the principal route from Toronto to points east. Accordingly, it became the site of numerous inns and motels, many of which still dot the road, particularly in Scarborough. Now some of these inns are being demolished to make way for townhouse developments. Kingston Road is a six-lane principal arterial road through most of Scarborough, narrowing to four lanes in Durham, with a speed limit for the most part. Public Transit History Kingston Road Tramway From 1875 to 1887 Kingston Road Tramway ran horsecars from Don Rver (Don Bridge - now Old Eastern Avenue Bridge) to Main Street (moved further east to Blantyre Avenue in 1878 to serve Scarboro' Heights Hotel). The single track route had three major stops (Don Bridge, Woodbine, Ben Lamond Hotel at Main Street and Scarboro Heights Hotel at Blantyre Avenue) running 12 times daily and 13 on Saturday in summer. The route ceased operation in 1887. Toronto and Scarboro' Electric Railway, Light and Power Company The Toronto and Scarboro' Electric Railway, Light and Power Company inaugurated a single-track radial service along Kingston Road from Queen Street as far as Blantyre Avenue, just east of Victoria Park Avenue, in
