Pittsburgh is known for its rivers. But many residents, like 90.5 WESA listener Judith Hoover, aren't sure where the bottom of each of the three lie.

A flood warning is in place in Pittsburgh through Sunday due to predicted heavy rainfall, and residents can expect the flooding to be similar to what happened last weekend.

Pittsburgh public safety officials are trying to determine why a rain-activated gate failed to automatically stop traffic from entering a low-lying roadway where four people died in an August 2011 flash flood.

The Pennsylvania Department of Transportation installed the $450,000 system in 2012, but it's now operated and maintained by the city. The system uses rain sensors that can trigger three swinging-arm gates and several lighted caution signals meant to keep motorists off Washington Boulevard.
