Changes Proposed to Trollheim Bridge

The National Park Service has released a Cultural Landscape Report and Environmental Assessment for improvements to Theodore Roosevelt Island.  The scope of the project includes changes to Bridge 31, which trail users commonly refer to as Trollheim Bridge due to the number of crashes and injuries that have occurred on its slippery surface.

NPS has proposed four alternatives.  All four alternatives include widening the bridge to 12 or 14 feet and replacing the bridge decking to provide a more even surface with.

More information on the project can be found here. The four proposed alternatives can viewed starting on page 268 of the Environmental Assessment.  Stay tuned for additional opportunities to provide public comment on which of the four alternatives you prefer.
