of Jarvis Street. In 1965, 62 yellow 'call boxes', containing phones for emergency assistance, installed by the Ontario Motor League, were fixed to poles on the shoulders. These remained in operation until the 1990s. In 1994, the Road Emergency Services Communications Unit traffic management system began operation on the Gardiner and Lake Shore Boulevard and stranded motorists became quickly detected by the CCTV cameras and operators quickly dispatch assistance. By 1966, rush hour traffic and collisions in the Jameson area meant that the Jameson westbound on-ramp was closed permanently during rush hours. That same year, after criticism of the safety of the expressway by Toronto coroner Morton Shulman, Metro started installing guardrails on the full length of the Gardiner and Don Valley expressways. In 1968, the speed limit was proposed to be raised from 50 mph to 55 mph (today it is 90 km/h). The expressway was already experiencing congestion at the time, and journalists openly questioned whether anyone could reach that top speed with the "horrendous volume of traffic" during peak rush times. In 1988, the unmaintained grassy hillside in the Sunnyside area on the north side of the Gardiner from Roncesvalles Avenue to Wilson Park Avenue was cleaned up and planted with floral logos, with of garbage removed in the process. The advertising, which pays for the maintenance and cleaning of the hillside, permits no slogans and no alcohol or tobacco logos. The logos are planted yew bushes and are maintained by an independent company on the land, which is owned by the Canadian National Railway. In the late 1980s, Metro Toronto proposed to widen the Gardiner to eight lanes from Strachan Avenue to the Humber, and extend Front Street from Bathurst Street west to connect with the highway. The widening proposal was never implemented as it depended on provincial funding which never materialized. Metro had planned the Front Street extension as part of allowing the Bay-Adelaide office complex and other development downtown to proceed. The Province did approve the Front Street extension, but the then-City of Toronto Council voted against it. The Front Street extension proposal was later resurrected as part of proposals to redevelop or dismantle the central section of the Gardiner. The old Gardiner and Lake Shore Boulevard bridges over the Humber River, which had been in service since the 1950s, were removed and replaced by new structures in 1998 and 1999. The old bridge
