Thought I would share photos of the 2 35' bridges we built on a new multi-use trail in Santa Cruz City open space, the Emma McCrary Trail in Pogonip. Mostly iphone photos, need to get some good ones of the completed bridges.
Excavation begins on abutments.
Concrete goes in. About 95 80lb bags per bridge. All hauled in by wheelbarrow about 500' to one of the bridges, about a half mile for the other (used a muck truck, still really hard work).
Beams get delivered. Had to move them to a different truck as they wouldn't fit under a railroad trestle on the way into the park.
Beams are treated 6x18 glue lams. 35' long, 976lbs. About $13,000 for 8 of them.
Beams were treated with waterproofing on top and ends. Moved in on cricket carts.
This one was a 450' trip straight down the hill. Used a porta-wrap to lower it slowly and safely.
Our arborist volunteer set up rigging for moving the beams across the creek.
Used a high lift jack to lift the beams up to drill the bolt holes.
Time to move the decking in. 5' rough cut 3x8 redwood fresh from the mill. VERY heavy. Went in the same way as the beams.
Railing posts in.
Railing taking shape. Design matches railing on historic building in the park (Grandpa's house in the Lost Boys movie!).
The final cut!
It was a huge undertaking for our club's first trail build, but with able and willing volunteers and generous donors we made it happen!
