MetroBus - Why it’s the right solution



Everyone in Bristol wants improved public transport, however recent news reports have highlighted that some Bristol residents don’t feel that MetroBus is the solution. In this post I want to advance a few reasons why it’s a good idea and debunk some of the reasons put forward for cancelling the scheme.

Benefit 1: Cost

The estimated cost of all three MetroBus schemes is £200M. Sounds like a lot but it’s cheaper than building a tram. Consider that in 2003 the Bristol Supertram was budgeted at £200M (or £250M in today’s prices) for a route which only went from Bristol Parkway to the centre. MetroBus goes a lot further than that and costs less.

A recent article in “The Economist” quotes stats from the American Public Transportation Association that the capital cost per mile of a streetcar (an American tram) is between $30m and $75m, while a rapid bus service costs anywhere between $3m and $30m.
The case is clear cut – Rapid Bus Services cost less than trams.

Benefit 2: Flexibility

If you build tram lines then only trams can use them. If it gets busy then you can’t quickly lay on more trams. Similarly if no one is using the tram then you can’t re-deploy the existing trams for other purposes.

If you build the MetroBus, then existing buses can be inexpensively modified to also use the MetroBus routes. This makes it much easier to increase/decrease capacity quickly.
With a tram you make two journeys, one to the tram stop and one on the tram. With the MetroBus your normal bus can use the MetroBus lanes and you are making just one journey.

The arguments above apply equally to conventional railways as they do to Trams, in fact conventional railways cost more and are less flexible.

Now to debunk a few of the reasons put forward by the opponents of the MetroBus scheme:

Reason 1: The MetroBus won’t have any impact on congestion, it will only increase bus passengers by 200 people, basically it won’t have any benefits.

These arguments involve selective presentation of the facts and do not give the full picture. The North Bristol package has a benefit-costratio of 2.34. This means we get back double what we pay in wider benefits. These benefits run to over £400M of which, £189M is reducedtravel time in the North Bristol area. To say the MetroBus is going to cost a lot of money and we’re not going to get any benefits back is clearly a load of rubbish.


First, What does exponentially actually mean? It sounds bad but is it £1M, £10M or £100M.
Second, cost increase alone this is not a reason to scrap the scheme. The actual questions are: Does MetroBus still offer significant benefits? Does MetroBus still offer value for money compared to other methods of transport? The opposition does not answer these questions.
However it is true that costs have risen between 2011 and 2014, I agree that this is unacceptable. The people who originally estimated the cost of this project need to be held to account. We need to know why and how it will be avoided in the future. We need to demand reforms to the project cost estimating process. This is the real argument but no one seems to be passionate about this.


The opposition to MetroBus paints this as an either/or issue. In fact we can - and are going - to have both. The project to re-open these rail lines is called MetroWest and funding of £81.4M has already been received.

Construction on the Hengrove Loop is due to start in 2020 however work on it has been paused while the Bristol Port Company carries out an assessment on the impact on freight traffic. The delays to this project are an example to us, somebody always objects! There are no easy solutions.

It’s obvious that re-opening the train lines won’t solve all the problems MetroBus does. For example, Emersons Green doesn’t have a train station yet a lot of new houses are being built in the area. How does Emersons Green get reliable public transport? If you want to build a new train station and train line here then you are looking at a very large cost.

Reason 4: Buses are worse for the environment than trams
This is simply not true. The MetroBuses will emit 25% less carbon emissions than a normal bus. If you think this is still not enough, then lobby the council for electric buses. Electric buses will still be cheaper than trams and they will be emission free. 

On the Feed Bristol project
Bristol City Council (BCC) has been supportive of Feed Bristol and the Avon Wildlife Trust:


  • BCC provided the Stapleton allotments for this project when Avon Wildlife Trust’s original site became unavailable.

  • BCC told Avon Wildlife Trust the size of their site would be reduced by MetroBus when they signed the lease three years ago.

  • BCC have waived the rent on the site and provide support from allotment staff free of charge.


It is undoubtedly a shame that MetroBus will lead to a reduction in the size of the Avon Wildlife Trust’s project. However, in the end I believe that MetroBus will lead to less roads being built, improve air quality and make Bristol a greener city. I do believe that the dedicated bus junction onto the M32 is needed. If you’ve regularly sat in traffic queuing for the motorway then you will know that the ability to avoid this is a major benefit.

We could go on all night, we could spend hours debating the pros and cons of cost benefit relationships, we could argue about whether there is enough time to re-design the route before we lose the funding and no matter how long we go on for there will always be more objections to answer. In the end, I believe George Ferguson when he says:


MetroBus is the right solution for Bristol.
