Roads: Motorway Lanes Closures

Volume 696: debated on Wednesday 21 November 2007

asked Her Majesty's Government:

Further to the Written Answer by Lord Bassam of Brighton on 24 October (WA 121), what hourly cost is attributed to a blocked lane of a motorway in the Defence Research Agency's report of heavy vehicle recovery practice. [HL271]

The report by the Defence Research Agency used a computer model and estimated a range of delay costs for blocking one lane of a three-lane motorway for 65 minutes of £29 to £18,528. This range is for traffic flow rates of between 1,000 and 2,000 vehicles per lane per hour respectively.

asked Her Majesty's Government:

What hourly cost the Highways Agency attributes to closing one lane of an ordinary motorway in the United Kingdom; and how this figure is arrived at; and [HL272]

What hourly cost the Highways Agency attributes to closing one lane of the M25 motorway in the United Kingdom; and how this figure is arrived at; and [HL273]

What hourly cost the Highways Agency attributes to closing an ordinary motorway in the United Kingdom; and how this figure is arrived at; and [HL274]

What hourly cost the Highways Agency attributes to closing one lane of the M25 motorway in the United Kingdom; and how this figure is arrived at. [HL275]

The Highways Agency does not have flat-rate costs for motorway closures. Instead, a cost must be determined on a case-by-case basis, as it is highly dependent on factors local to the individual stretches of motorway, including duration and time of closure. Such a cost would be in the order of £5,000 to £10,000 per lane per hour and is made up of two parts; the actual cost of the traffic management measures deployed, and the delay and changes in vehicle-operating costs to road users.
