Who, or what government department, was responsible for designing the new roundabout at the beginning of Crewe Road by the airport? I ask because it is working so well, solving a serious problem at a notorious black spot for traffic accidents. I think the designers should get public recognition.


Auntie’s answer: The roundabout is the work of the National Roads Authority. With traffic issues often highlighted by readers, I am happy to report on something that does seem to have solved a dangerous problem. And that is one of the reasons the NRA is being presented with its second Ask Auntie Award, having been one of a number of recipients in January 2017.

In addition to the job well done on the roundabout, which you can read more about below, the NRA is one of those departments whose people always seem to try their best to answer the many readers’ questions that I send them.

Back to the roundabout. I have seen too many accidents, both serious and minor, at the spot you asked about. I feel confident in saying that as long as drivers make sure they properly follow the rules for negotiating a roundabout (and that is by no means a given), that particular spot should be relatively trouble free. For anyone who needs a refresher, I have covered roundabouts previously (see Unsure about roundabout right of way).

In addition, in case you are interested, an NRA official explained that the roundabout was designed by its engineering department, which, along with its planning people, “review and provide comments on the design to fine tune it to make sure it fits the location”.

Designers consider several factors, specifically the traffic flows on each leg as well as the daily traffic count. Therefore, it should not be surprising that the design process usually takes longer than the actual construction, but that also depends on location.

The official added, “In this case, the intersection had been looked at for quite a long time before a decision was actually made on using a roundabout.”

I, for one, am glad the NRA took the extra time to make sure they got it right.
