The Keniston Bridge – Andover, NH

Andover, NH is home to two covered bridges.  The first bridge is the Keniston Bridge built over the Blackwater River in 1882 by Albert R. Hamilton at a cost of $745.57. 

The lattice work on the side is not just ornamental but also provides support for the bridge.  A lattice truss structure allows a substantial bridge to be made using planks and lower-skilled labor, rather than heavy timbers and more expensive carpenters.  It’s also easier to handle and move planks rather than timbers.

The covered bridge is next to a railroad bridge.

The town rehabilitated the bridge in 1981.  To do work on the foundation or abutments, the engineers lifted it from its foundation using two cranes and moved it to a temporary site.  The problem was that the site was only a few feet above the water level. The engineers had to work quickly to finish fixing the abutments and return the bridge to its place before heavy rains and rising waters caused the river to rise and damage the bridge.

    I particuarly like how the trees seem to frame the bridge in the first photo. Thank you for including the information about how the bridge was constructed. I learned something!

    The lattice work is so pretty and it provides so much light and support! These bridges are all so different. It’s interesting how varied they all are. These are great shots you’ve created! It’s so green and lush where you are. Thank you Chris!

      Thank you, Sandra. I like the openness of this bridge. Some can be very closed in. Yes, it is green here. We’ve had a fair amount of rain recently. Have a great evening. Take care.

      Thank you, Andi. I find that I like the open bridges more than the ones that are closed in at the side. They do have a Hans Christian Andersen feel to them. Have a great day.
