Crawlerway

The Crawlerway is a 130-foot-wide (40 m)[2] double pathway at the Kennedy Space Center in Florida. It runs between the Vehicle Assembly Building and the two launch pads at Launch Complex 39. It has a length of 3.4 and 4.2 miles (5.5 and 6.8 km) to Pad 39A and Pad 39B, respectively. A seven-foot (2 m) bed of stones lies beneath a layer of asphalt and a surface made of Tennessee river rocks.

The Crawlerway was originally designed to support the weight of the Saturn V rocket and its payload, plus the Launch Umbilical Tower and mobile launcher platform, atop a crawler-transporter during the Apollo program. It was also used from 1981 to 2011 to transport the lighter Space Shuttles to their launch pads.

Construction of the Crawlerway connected Merritt Island with the mainland, forming a peninsula. The main vehicle access road to and from the launch pads, the Saturn Causeway, runs alongside the Crawlerway.

ConstructionEdit

The Crawlerway is composed of two 40-foot-wide (12 m) lanes, separated by a 50-foot (15 m) median. The top layer is Tennessee River gravel, 4 inches (10 cm) thick on the straight sections and 8 inches (20 cm) thick on curves. Tennessee River rock was chosen for its anti-spark properties. Beneath that is 4 feet (1.2 m) of graded, crushed stone, resting on two layers of fill.[2] By 2013, a project to repair and upgrade the Crawlerway was undertaken, the first time since it was constructed that the foundation had been repaired. Additional rock was added to the surface in June 2014.[3]
