[Iron Munro]

The Brooklyn Bridge (built in 1883) and other structures of the era were built of solid limestone, granite and mortar, not steel reinforced concrete.

The bridge anchorages, bases and towers are solid structures of stone masonry.

Each of the masonry towers contains about 90,000 tons of limestone and granite stone blocks and tops out at 276 feet in height.

The stone war largely mined about 100 miles away in the foothill;s of the Catskill mountains and the huge blocks were transported by barge down the Hudson River to the bridge site.

The bridge is now over 130 years old and still as solid as the day it was built.

What is that lighthouse near the bridge?

It has a 3-ton weight limit on it for vehicles, however.
