What might we expect for the viaducts?

Here are a few photos of a viaduct on the National Highways A14 Cambs project, from back when we went on a site visit to try and get a better understanding of what a large road construction project is like.  We were told this viaduct is similar to what we might expect if the proposed LTC goes ahead.

 

Green bridges

When you think of green bridges you would be forgiven for thinking of a wide bridges with plants, hedges, with wildlife happily wandering safely across.  The reality is the kind of bridge you’re most likely thinking about is actually what is known as a wildlife bridge rather than a green bridge.  And certainly not the reality of what NH/LTC are proposing for the LTC.

At consultations we’ve been told that the ‘green’ bridge at North Road for example would have little if any hedgerow for example due to visibility issues for traffic.

Another example, the Thong Lane ‘green’ bridge ends with a T-junction, ultimately guiding wildlife to  the danger and risks of a busy road junction.  Should this really be considered a ‘green’ bridge?  (Click image to enlarge)

Thong Lane green bridge

How is wildlife supposed to know where these so called ‘green’ bridges are?  Even if it does there are clearly no guarantees they will offer safe passage.  There’s no proven mitigation for bats when it comes to new roads either.

So when you hear NH/LTC talking about ‘green’ bridges and the ‘greenest’ road every built in the UK, just remember that sadly things are not always as they like to portray.
