Chesapeake Bay Bridge Tunnel
|
|
One of only ten bridge-tunnel systems in the world, the Chesapeake Bay Bridge and Tunnel spans over 28 kilometer (km) across the mouth of the Chesapeake Bay in Virginia. The bridge consists of two double lanes with the northernmost being 12 meter (m) wide and the southernmost being 10 m wide. When parallel, the two double lanes are spaced 66 m apart but come together to go through the tunnels, which make up over 3.4 km of the bridge system. The bridge connects the Delmarva Peninsula with Virginia Beach and the Hampton Roads metropolitan area. The Chesapeake Bay Bridge Tunnel has a few bends in it with the two largest segments lying 18 degrees and 39 degrees east from true North (see photo).
The high reflectivity of the bridge contrasts with the water background, which makes it a suitable line target for medium resolution satellites (30 m or larger GSD). At resolutions higher than 10-15 m GSD bridge structure and features make this less suitable for analyzing Line Spread Function (LSF). Users may wish to consult high-resolution imagery to understand any local changes or features present on the bridge that would impact analysis.
