Cut one length of 250 mm and one length of 200 mm spaghetti and place on the cutting mat 50 mm apart.The 200 mm length should be placed so it is 25mm in from each end of the 250 mm piece....i.e. the centres of both parts line up.Use tape or blu-tac to hold the parts in place.

| Main supports for Side of Bridge |
Cut nine lengths of spaghetti to 50 mm long to act as cross braces.
 |
| Cut nine lengths 50 mm long as cross braces |
Start positioning the cross braces so they fill the space between the main supports. These should be positioned every 50 mm starting in from the end of the 250 mm long piece of spaghetti.
 |
| Start positioning the cross braces |
Once in place tape the cross braces in position so they will not move during gluing.
 |
| Tape the cross braces in position so they can be glued. |
Add a cross brace at the end of the 200 mm long support at the left and right hand ends.
 |
| Add cross brace at the end of the upper support piece on the left end |
 |
| Add cross brace at the end of the upper support piece on the right end |
Fit in the remainder of the cross braces so there are nine in total, one every 25mm spacing.
 |
| Fill in the remainder of the cross braces |
Apply glue to the joints.Leave to dry overnight.
 |
| Glue up the joints. |
Add the outside end diagonal parts and glue up.
 |
| Diagonal brace goes at the end of each side piece |
Add the diagonal brace at the other end of the side pieces.
 |
| Add diagonal bracing at other end of side piece |
Start to add the internal diagonal bracing inside each rectangle observing that the direction causes no parallel braces but forms triangles.
 |
| Insert diagonal braces in all rectangle spaces. |
The finished side pieces should be completely braced and glued up. Leave overnight to dry.
