Bridge Building

Today, Mr. Taylor (aka Mrs. McDougall's dad), came in to share everything he knows about bridges. He has been building bridges for about 50 years.  We even got to build a bridge that was strong enough to hold Avery.

Here are some of the things that resonated with us:

-there are two different types of people that have to work on jobs - civil engineers and contractors HLA

-a bridge has to be strong and stable. It is important to look at the weight limits of a bridge before you go over it. BB

-we build bridges over train tracks, gorges, roads, water and other obstacles JH

-it takes lots of materials to build a bridge such as concrete, wood, steel and sometimes even stone/brick RT

-concrete is made out of sand, water, stones, cement AT

-contractors need to be very safe and follow safety guidelines when building a bridge CB

- bridges are built to hold a specified weight. The older bridges were not built to hold as much weight NG

- building a bridge takes a long time and it has to meet safety inspections PT
