We had to tie them down and drive slow, because there was no alternative. The plan is to go to the store tomorrow, purchase screws and then begin building. Once the basic structure is up, we will buy more lumber for railing.___________________ __________________________________ ___________________________ _ Comment/Suggestions:Tuesday, February 21, Activity: Went to the Lowe’s in Canton Do not underestimate the2012 Marketplace to purchase two 8” X 8” X effort required to move 6x611:00 a.m.-1:30 p.m. 16” lightweight concrete blocks, one beams.

In the future, cut all of the 2x4s, moved the materials either choose to only use one to the site, dug holes for the beam, or just make a rope foundations and set the beams. bridge. Commentary: After that, I marked and cut all of the 2x4s into three-foot lengths. My dad and I drove as close as we could to the site, and we walked the materials in the rest of the way. Holes were dug for the concrete blocks,
which serve as level surfaces for the 6x6 beams, and then we positioned the beams so that they spanned the creek. We ended the day by screwing in decking on either end, and all the rest will be screwed in tomorrow. Tomorrow may allow us to put the safety railing in as well. _____________________________________________ __________________________________ Comment/Suggestions:_ _ The measurements forWednesday, February Activity: Started the day by lining up lumber are based on when it22, 2012 all the decking with the cross beams is wet and fresh, not when it11:00 a.m.-2:00 p.m. and then screwing the individual is dry.

Commentary: All of the decking had to be perfectly in line, so my dad and I lined them up and snapped a chalk line across the boards so that they would stay on track. That same line was also used for the placement of screws on one side. Space was allowed in between the boards, since moisture and heat will change the volume of the boards over time. When we ran out of 2x4s, we took the time to resupply and also gather our materials for the next day. Ideally, decking should be finished tomorrow.

The creek had to be rerouted, so I dug a channel around the site for the columns, and then I created multiple dams upstream to hold back water. Even further upstream, I dammed the creek and routed it to flow into another creek that is away from the bridge. Commentary: Today was mainly a tedious day. All of the remaining lumber was cut to size, and then holes were dug for the columns. Various earthworks were also created for rerouting the creek.
