Win Cash For The Holidays! Netting Concrete Before It Can Fall pocked surfaces, or corroding steel reinforcing bars, Schwartz said. Since July, DOT has spent about a (1 million a month on the pro-; gram, completing 20 elevated road- i ways and beginning work on an-! other 22. Several viaducts, 1 including segments of the FDR Drive, the Brooklyn-Queens Ex-' pressway and the Williamsburg Bridge, warranted immediate work, Schwartz said. During the next three years, DOT hired will systematically remove loose concrete and install wooden planking and netting on the remaining viaducts. In October, Mayor Edward I.

-Koch also asked for a budget amendment of about (10 million to help defray the cost of the emergency program. Its also clear that, over the long run, we have to find a substitute for Balt. It is destroying our concrete and our steel reinforcing rods, Schwartz said. Salt combines with water, oxygen and dirt to set up an electrical reaction 1 thats like a slow-motion explo- sion, he said. DOT researchers plan to test several Balt alternatives this winter, Schwartz said.

This month, DOT is installing a sophisticated sensor system on the Brooklyn Bridge to monitor temperature, wind chill, moisture and salt content on the roadway and relay' those conditions to DOTs command center. We hope this information will help us control the amount of salt we spread so we can avoid over-doing it, Schwartz said. On the Manhattan Bridge, cinders will be substituted for salt. The Williamsburg Bridge will be -the test site for calcium magnesium acetate, salt Substitute. But its clear we have to do something.

We may not have earthquakes, but every day there are heavier trucks than ever entering this city, and their heavy pounding is loosening concrete on roads that are in need of repairs," Schwartz said. By Katherine Foran When a 400 pound chunk of concrete fell from the outer roadway, of the Williamsburg Bridge last month, driven beneath were not in jeopardy thanks to protective netting that had been installed just the previous week. The netting is part of a (30 million, three-year program the city Department of Transportation began this summer, prompted by a fatal accident last June 1, when concrete dropped from the underside of the FDR Drive crushing a driver below, DOT officials said. The June accident also has inspired new efforts to find substitutes for the salt thats corroding city streets, DOT Chief Engineer Samuel Schwartz said. Under the new program, DOT has targeted about 400 bridges and viaducts with flawed concrete that the city will need to chip away or shield with -wood or netting, Schwartz said.

There is veiy little risk to drivers today, and were catching whatever potentially dangerous conditions are out there through this three-year program. But were erring on the side of caution, Schwartz said. Many of the flawed structures were already scheduled for mqjor reconstruction through the next decade, but the (30-million repair program will help eliminate hazardous conditions in the meantime, Schwartz said. After the June accident, the city combed through inspection reports to identify potential trouble spots and examined concrete road decks about the same age as the FDR viaduct, Schwartz said. It was imperative that we come up with a program to protect the public from similar hazards that might exist elsewhere, Schwartz said.

Inspectors also surveyed viaducts, bridges, road decks and other structures that showed any evidence of deteriorating concrete, including cracks, crumbling or By Shopping At New York Newsday Advertisers!
