Deep Highway culvert installation, fish pass
Deep Highway culvert installation, fish pass
(OP)
We are looking at installing a deep(50') 10' diameter cmp fish pass culvert. Considering installing in 2 stages so we can keep 2 lanes of traffic and a bike path open. I am looking for ideas on how to temporarily shore up the excavation longitudinally along the centerline of the highway. I am working with a cut approx. 45 feet deep in Sandy gravel soils, with traffic loading along top of cut. Any tips would be greatly appreciated.
Thanks
Thanks

While I know nothing about this specific project, I've been told in the past that the fish like larger openings. So one large pipe is much more effective as a fish passage than several small pipes. As it was explained to me, the fish don't like tunnels, so a larger pipe is less "tunnel like" than small pipes.

This seems like it would be more preferable than open cutting in loose soils to that depth.
