DOVER — Dover International Speedway has completed two projects that extend SAFER barriers by almost 500 feet along the backstretch and into the entrance of Turn 3 and expand the pit stalls along pit road by 2 feet each. The work comes before the Monster Mile’s latest NASCAR tripleheader weekend on May 13-15. New asphalt has also been added along the area behind pit road, from the entrance of the NASCAR Sprint Cup Series garage down to the Start-Finish line.

Facts on the recent construction are listed below:

• 479 feet of Steel and Foam Energy Reduction (SAFER) barriers were added to the one-mile, high-banked, concrete oval.

• Seventy-eight feet of standard SAFER barriers were added to the existing inside backstretch wall and 401 feet of SAFER barriers were included in front of a new, steel post inside wall on a newly placed stretch of concrete in front of the grassy area at the entrance to Turn 3. The Monster Bridge near the Turn 3 entrance sits above the new construction area.

• The SAFER barriers are 40 inches high.

• Along the new stretch of wall, one foam block is placed every 5½ feet within the SAFER barrier to maximize safety from crash impacts.

• 190 cubic yards of concrete, 7-feet wide and 18 inches deep was added to the track.

• Along pit road, three pit stalls were eliminated, leaving space for 40 cars. Each pit stall was increased 2 feet in length, to 34 total feet. All stalls remain 16 feet wide.

• 550 feet of new asphalt was added between the NASCAR Sprint Cup Series garage entrance and the Start-Finish line.

The May 13-15 NASCAR weekend includes the Camping World Truck Series race on Friday, May 13, the “Ollie’s Bargain Outlet 200” NASCAR XFINITY Series Dash 4 Cash race on Saturday, May 14 and the “AAA 400 Drive for Autism” NASCAR Sprint Cup Series race on Sunday, May 15.
