detail of the 17 miles long bridge

I took the above picture while flying back from L.A. where I visited my daughter.
This is the Chesapeake Bay Bridge, a four-lane 20-mile-long vehicular toll crossing of the lower Chesapeake Bay.
I drove on it several times on my way to Philadelphia on our frequent trips to visit the hubby’s family.

Here are some technical details about the bridge.
The facility carries US 13, the main north-south highway on Virginia’s Eastern Shore, and provides the only direct link between Virginia’s Eastern Shore and south Hampton Roads, Virginia. The crossing consists of a series of low-level trestles interrupted by two approximately one-mile-long tunnels beneath Thimble Shoals and Chesapeake navigation channels.

Total Length (including approach roads):
23 miles
Length Toll Plaza to Toll Plaza:
20 miles
Length Shore to Shore:
17.6 miles
