contrasts

The Carlton Bridge in Bath, Maine shows two distinct conditions, a painted lift section and two very rusted connecting sections.

The bridge was changed from carrying rail and road traffic to rail only when the Sagadahoc Bridge opened in 2000. The new bridge carries a road high above the river with space for boats to pass underneath.

I find it very interesting that the lift section has been maintained in good shape while the connecting non-lift sections have deteriorated to a state of rust. An article in the Bangor Daily News on March 23, 2015 titled "Rail officials say rust will force decision on 88-year-old Bath bridge" describes the choice that must be made, repair or remove.
