We have been doing a ton of work. More ditching, raking, and single track building.
We did build the bridge we needed on the trail connecting Just a Bunny to Tom, Dick and Harry. I LOVE doing trail work here vs working with clubs doing work else ware. We are sooo much more efficient. For this bridge I did once again glue up some arched beams. Once one has the jig layout, and the system "down", it does not take long to glue up a beam. I also had cut all my decking ahead of time. I was able to drive to within maybe 200 feet from where the bridge was going to go. I had everything all loaded and awaiting my wive's arrival. An hour later we had a bridge built.

I was able to carry the 2 beams myself in one trip, while Laurie carried my first needed tools, and materials. I placed the beams across the brook, and then screwed a piece of decking, on the bottom of the beams, fasting the two together. I then flip it over and figure out the best placement. I them move it, so I can dig down to sink it into the ground a little, and to level the ground. I then start fasting the decking. As I work my way across the bridge, I do add a couple 2x4 cross braces. Laurie is carrying stuff down as I work. As I am finishing the decking, she is gathering rocks. I we place them on that first bottom piece of decking that fastens the two beams together. They are longer than the bridge is wide. It adds some stability to the bridge, and give me something to set the rocks on. We had all the tools back up to the RTV.. and hour from when we left the house.
It of course helps that we are leaving from the house, vs having to drive some where else first. While in some cases I have to carry stuff more than a few hundred feet, I can generally drive fairly close, vs carrying by hand from the house. We have dual track interspersed with our single track, through out the network.
