Innovative technique to install two bridges in one weekend on A14 upgrade...

How do you build two 1,000 tonne bridges over a very busy road while (nearly) keeping the road open throughout? You build them at the side of the road and wheel them into place at the end! This is exactly what the A14 Cambridge to Huntingdon upgrade team has been doing over the past few months. They have built four abutments to support the new bridges as well as two bridge decks at the side of the live carriageway, and are now ready to wheel the bridges decks, each measuring 44 metres, into place on top of the abutments.

Now the team has released this engineering video to show exactly how they plan to tackle the challenge – and it involves a very big, remote controlled platform on wheels.
