Good morning Leo,
This email is a follow up to your comments regarding the 16th Avenue EA Study and the Highway 404 HOV widening construction.
Thank you for your suggestion to implement dual left-turn lanes from 16th Avenue eastbound to Highway 404 northbound. In order to implement dual left-turn lanes, 16th Avenue would need to be widened even further at the intersection to five lanes, requiring more property and/or a larger bridge at Highway 404. Dual left-turn lanes on Regional arterial roads would require changes to the timing of the traffic signals which may cause delays to other movements at the intersection. The wider cross section would also increase the crossing distance and the duration of the red light.
Regarding your comment about dedicated right-turn lanes, when Regional roads are widened from four to six lanes, no additional auxiliary right-turn lanes are provided. At intersections, the Transit/HOV lanes will also function as right-turn lanes for single-occupant vehicles. Buses are expected to arrive every 15 minutes, which should give sufficient opportunities to make right turns. Right-turn lanes would also increase crossing distance and red light time.
Based on the York Regional Council-approved2018 10-Year Roads and Transit Capital Construction Program, the first section of the 16th Avenue road improvements, between Leslie Street and Woodbine Avenue, is expected to begin in 2021. There are portions of this section at Highway 404 currently in the detailed design phase. The Ministry of Transportation Ontario (MTO) is leading the design assignment which will involve advancing some of the 16th Avenue improvements as part of their Highway 404 HOV widening construction. York Region is working closely with MTO in this process, with meetings every couple of weeks. MTO anticipates to begin work at 16th Avenue and Highway 404 in 2019. By copy of this email, your feedback regarding the interchange at Highway 404 and 16th Avenue has been forwarded to the MTO for their consideration in their Highway 404 HOV widening project.
The remaining sections of the 16th Avenue road improvements are not currently in the 10-Year Program; therefore, construction is at least ten years away and detailed design has not yet begun.
Thank you for your interest in the 16th Avenue EA Study, and for taking the time to provide us with your suggestions. Should you have any further questions, please do not hesitate to notify us.
