The Brownsville Iron Bridge, Market St. near Bank, was built in 1836-9 of iron forged in local furnaces. A tablet asserts that it was the first iron bridge west of the Alleghenies. Henry Clay, on one of his journeys, was dumped into the bed of Dunlap's Creek here when his carriage overturned. According to a local chronicler, Clay “gathered himself up with the remark that Clay and mud should not be mixed in that place again.” Shortly after Clay returned to his senatorial duties in Washington an order was issued for the construction here of an “iron span, carrying the road high above the stream.” ~ Pennsylvania, A Guide to the Keystone State, WPA 1940
