The duration of ramp closures required to implement an alternative will be measured and considered as part of the evaluation of alternatives. A Technically Preferred Alternative (TPA) will be presented at Public Information Centre (PIC) No. 2. The TPA will then consider residual effects and attempt to minimize these effects, including ramp closure durations. One mitigation measure may be to program construction, of more than one bridge project at a time, so that total traffic disruption (including ramp closures) can be reduced / minimized.
