Email by clicking the link on the right side of the page that says “Email Us” Be sure to write “Bridge Werks” in the subject line.. We will need to know what Type bridge you want in addition to the Scale (HO, O, etc). Include the overall length of the bridge and if it is a trestle bridge that is on an incline. If it is a trestle bridge we will need to know the terrain on which it sets and height dimensions as well as length.. We will need to know if it will be made of popler, redwood or Bass wood and if you want it weathered or not .(it is best if you want a weathered bridge to let us do the weathering as it is very difficult to stain after gluing) We do not paint our bridges but you many if you wish. If there is anything else we need we will contact you through email. HO Scale bridges are made of Bass wood or popler.. Larger scale bridges may be built from any type wood you wish. We only build wood bridges We have our own formula for weathering and it is representative of our weathered bridges in the photo gallery. Once supplied with all necessary information we will eMail you with a quote.
