DOVER, Del. (AP) Dover International Speedway started work Monday on a new catch fence that will be installed in time for the 2015 NASCAR season.
The fence will stand at 21 feet, up from its current 15 feet. The new $2.9 million fence will be installed by Smith Fence, a Florida-based contractor that has performed similar installations at other facilities on the NASCAR circuit.
Other improvements at Dover in recent years include the installation of SAFER barriers, the widening and lengthening of pit road, new fan care medical facilities and many fan experience improvements.
Jeff Gordon won Sunday's Sprint Cup race at Dover. Dover is the site of two NASCAR weekends each season.
Dover Motorsports COO Michael Tatoian says a NASCAR vehicle has never become airborne and hit the catch fence.
