Pennsy Supply is the leading manufacturer of aggregate, sand, asphalt and concrete throughout the North and Central Regions of Pennsylvania, serving the region for more than 90 years. Their recently constructed Millard Quarry Tunnel is a 259-ft long, 10-ft diameter structural plate pipe buried beneath a 50-ft tall limestone stockpile with a designed storage of roughly 5100 tons.

The structural plate pipe is used for its ease of construction, its strength, and its ability to host a conveyor system in which aggregate is metered into the tunnel through a series of hopper openings before being conveyed to another part of the process.
