<P>When the flames were still full of life, the Georgia Department of Transportation (GDOT) was staring at plans from about three decades ago.The I-85 bridge over Piedmont Road in metro Atlanta was burning on March 30,mobile traffic light sale in uk but officials were hopeful portions would be spared, and they wanted to be ready. So before damage could be assessed, before emergency responders even had the upper hand on the fire that was engulfing the bridge, GDOT had the original designs out and started considering what might be needed in way of repair.</P>
<P>“We knew, as did the public, that one span had to be replaced,” Marc Mastronardi, GDOT construction division director, told Roads & Bridges.According to Mastronardi, solid steel roller wheels industrythe existing bridge had AASHTO type 5 prestressed concrete girders in place, which are no longer common. However, GDOT designers were confident a special prestressed concrete girder could be designed and allowed for retrofitting with today’s specifications.</P>
<P>When the smoke cleared, six spans—three northbound and three southbound (100-ft section)—were lost due to the heat damage, and the salvageable substructure was limited to portions of the columns. C.W. Matthews Contracting Co. Inc., which in 2001 repaired I-285 over S.R. 400 following a tanker fire,asphalt repair truck for sale was selected as the prime contractor for the rebuild.</P> |
