Allendale Road Bridge

Posted July 6, 2010, by Nathan Holth (form3 [at] historicbridges [dot] org)

This bridge is either to be or has been demolished. Given that the bid package was let in April 2009, it seems likely the bridge is already a goner. Attached is a diagram from the bid package plans showing removal and replacement plan.
