In order to install a bike and pedestrian overcrossing, the City of San Ramon will need to stop traffic on Bollinger Canyon Road for nine days, forcing roughly 40,000 trips to be rerouted each day. As the winner of Replica’s Road Closure Scenario contest, the City received a free road closure Scenario to better understand the potential impact of rerouting these 40,000 trips and inform appropriate diversion plans and signal modifications given the forecasted traffic impacts. We’re sharing the results of that scenario — which took less than 1 week from start to finish — below.
