CASE STUDY

# How Pittsburgh Built Bike and Pedestrian Safety Into Fern Hollow Bridge After Its Collapse

##### When Pittsburgh’s Fern Hollow Bridge collapsed, the headline-making event left city residents without a critical connector between neighborhoods that had stretched through one of the city’s most popular parks.

##### City officials were on the clock to rebuild as quickly as possible, but they also hoped to improve the insufficient bike and pedestrian infrastructure on and around the bridge to improve safety for all road users.

##### See how Pittsburgh used StreetLight to:

- ##### Complete the Fern Hollow Bridge rebuild in less than 1 year
- ##### Design a shared-use path to increase safety for walkers and bikers
- ##### Diagnose dangerous traffic patterns leading up to the bridge
- ##### Go back in time to analyze typical traffic conditions prior to the collapse

##### “We turned to StreetLight to better understand how this intersection worked before the bridge collapse. This data was crucial to address safety in addition to the new complexity of different bike configurations.”
