Here is the first project that I am currently working on. I was asked to make a girder bridge for this layout ;

Above you can see the gap that needed spanning . Originally the plan was to use Wills vari-girder but after rummaging around in a few boxes none could be found , so I decided to see if I could scratchbuild something suitable ;

Here it is after painting mocked up , hopefully no one will notice there's no rivets or bolts holding it together !
