Rubber sidewalks

A Philadelphia official wants the city council to look at whether the city's sidewalks should be made of rubber.

City councilman Jim Kenney recently toured Chicago to see environmentally-friendly city projects there. He came back with a number of ideas on which he plans to hold hearings.

One is using rubber for sidewalks.

No, don't expect to see people bouncing down the street. Kenney says the rubber is very solid - probably harder than a running track.

He says rubber sidewalks are made from recycled tires. They don't crack, and they last longer than concrete.

Kenney says rubber sidewalks could also reduce the number of slip-and-fall accidents and the resulting lawsuits.
