Hey Dave,

I wanted to mention a possibility to you regarding a project we hope to start fall of 2022 - the replacement of Avery
bridge 27 on HWY 221. This bridge spans the Linville River – here’s the location.

I don’t think I will need to notify for the 401, but I wanted to get your thoughts about something. The plans/permit
drawings show a large causeway for the removal of the existing bridge. The new bridge will be built upstream and also
calls for a causeway as well, since we will need to dewater in order to build the new bridge supports.

Right now, I’m hoping/planning to not build the causeway originally designed for removal of the existing bridge (we will
still build the one needed for the new bridge). As you can see from the photo, the middle support is in the river, but it is
rocky and shallow. The other supports are completely out of the water or on the edge of the stream. As a result, I think
it will be a perfect place to take a clean, non-leaking trackhoe out into the river and pull the middle support over / or
hammer and remove the pieces, like we did at Ashe 355.

If we do this, I would definitely let you know ahead of time, and when it would occur, but wanted to give you a heads up
in case you had any initial concerns. I’d also contact NCWRC in case they wanted to survey/relocate any animals of
concern (hellbenders shouldn’t be there, since it is in the Catawba drainage, but I’d let them know our plans just in case
they had concerns).

I’m not sure who our contractor will be, and if I don’t have confidence in them, then we won’t try this approach.

In short, I wanted to see if you had any initial issues with this approach? That’s not to say you couldn’t have reservations
that develop later on, but wanted to go ahead and mention. It should result in much less impact / much smaller
footprint.

Thanks,

Kevin
