CHARLESTON, S.C. (AP) - Charleston officials are showing off a sidewalk repair system that are designed to save time and taxpayer money.
A demonstration is being held Monday in the West Ashley section of the city.
Instead of breaking up and then pouring new cement on sections of sidewalk pushed out of line by tree roots, the city uses a machine to lift the entire concrete panel of sidewalk. Workers then cut the tree roots underneath and put the panel back in place.
Under the old method, it cost about $500 to replace a section of concrete. With the new system, it costs only $71 and repairs are made in a day.
During the past two years, the city has used the system to replace almost 6 miles of sidewalk.
