Line 60: ==Rehabilitation, replacement and abandonment== When opened in 1931, tolls were collected in order to retire the bonds issued to finance construction. ~~however all~~All tolls were lifted twenty-two years later on October 31, 1953 when those original construction bonds were paid off. As the bridge approached its seventieth anniversary with the turn of the century, however, a series of safety inspections made by the Maine Department of Transportation revealed that over those seven decades the structure's two main suspension cables and the many vertical bridge deck stringers had become seriously corroded thereby deteriorating their ability to support the deck, roadway and the traffic that crossed it. These engineering studies made it clear that the bridge required immediate major rehabilitation and eventual replacement.<ref>{{cite web\| url = http://www.waldohancockbridge.com/waldo-county-bridge/hisfacts.php\| title = History\| work = Waldo–Hancock Bridge Replacement Project\| publisher =Maine Department of transportation\| accessdate = May 1, 2006}}</ref> [[File:Waldo-Hancock_Bridge,_Bucksport,_ME_in_July,_2007_after_abandonment.jpg\|thumb\|left\|The closed Waldo-Hancock Bridge in 2007 still showing its temporarily repaired cables.]]Work was undertaken to rehabilitate the bridge starting in 2000<ref>{{cite web\| url = http://en.structurae.de/structures/data/index.cfm?ID=s0001116\| title = Waldo–Hancock Bridge\| publisher = [[Structurae]]\| accessdate = May 1, 2006}}</ref> by [[Cianbro]] and Piasecki Steel Construction Corp. with cable work by Williamsport Wirerope Works Inc, by focusing on strengthening the cables. The two cables were done separately, one a time. Piasecki Steel Construction Corp., Castleton, N.Y., rehabilitated the north cable in 2002. At this point the bridge was discovered to be beyond permanent repair and would have to be abandoned and replaced by a new structure to be built adjacent to the aging bridge.<ref>{{cite web\| url = http://www.bridgemeister.com/pic.php?pid=172 \| title = Waldo–Hancock Suspension Bridge\| publisher = Bridgemeister.com \| accessdate = May 1, 2006}}</ref> Work then shifted to temporary strengthening. For the south cable, MDOT in August 2003 hired Pittsfield, Maine-based Cianbro Corp. under a $4-million emergency contract.
