Paving on the Bristol Motor Speedway project in Bristol, Tennessee, US has finished, with the project on schedule for its first race of the season on 25 August, the Nascar Sharpie 500. Demolition of the old track was completed on 26 March this year and Speedway Motorsports Inc (SMI) has been working round the clock to finish the US$ 8 million overhaul of the 0.53 mile (0.85 km) long, 40 ft (12.2m) wide track. SMI decided to repave the track using continuously reinforced concrete because it would allow the surface to move incrementally. The gradient of the banks was increased from 50 to 57%, and a pedestrian tunnel leading to the in field was also constructed. The paving work was carried out with a Gomaco SL-450 and several work bridges.
