The Lehigh Valley isn't much on history, neither Allentown or Lehigh County. The 1824 stone arch Reading Road Bridge is only still standing because of my efforts. It's sister bridge from 1828, Schreibers, may now be closed by the State. Since the 15th Street Bridge(Ward Street) was closed for replacement, Schreibers has taken an incredible beating. Although posted for 3 tons, it has been battered by tractor-trailers no less than half a dozen times. In a further assault to the bridge, Allentown dropped the ball, and allowed the State to make Oxford drive/24th Street bridge one way for repairs, increasing the burden on the old stone bridge.

UPDATE JANUARY 2017: Although, the new 15th Street Bridge opened about 18 months ago, Allentown has yet to repair the smashed walls on the Martin Luther King side of Schreibers bridge. In fairness to Allentown, they were repaired once during the closure of the 15th Street Bridge, but then were smashed again. Now that the 15th Street Bridge is complete, it's way overdue for the city to make final repairs on the historical bridge walls.
