Interesting. I grew up in Lockport, Illinois. There is a lock on the canal there. We used to have two, through truss swing bridges there. One of them is mentioned on this web site. Also, the 135th street bridge mentioned in Romeoville is nicely preserved along the side of the canal now days. It is interesting to hear from a resident of another Lockport. I think there is a Lockport New York, also.
As a citizen of Lockport, I would like to state that this bridge needs to have the rust taken care of and needs to be repainted badly. A group of citizens, quite a while back, tried to scrape off as much of the rust as possible and then it was painted. This was done only on the thoroughfare section. We did not go on the outside of the bridge nor under the bridge.
It really needs to have a professional job done NOW to preserve this historic bridge.
there is a train bridge north of lockport called black bridge.
