I found this handy post online <a href="https://banprivatecarsinlondon.com/2017/06/01/cycling-infrastructure-shopping-list/" rel="nofollow">https://banprivatecarsinlondon.com/2017/06/01/cycling-infrastructure-shopping-list/</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9259#post-96605 Fri, 11 Jan 2013 23:32:01 +0000 kaputnik 96605@http://citycyclingedinburgh.info/bbpress/ <p><strong>Motorway</strong></p> <p>M74 (extension<br /> Actual cost = £692,000,000<br /> Length (km) = 8<br /> Cost/km = £86,500k<br /> <strong><br /> A-road (dual)</strong></p> <p>Aberdeen western peripheral route (estimated)<br /> Actual cost = £395,000,000<br /> Length (km) = 29<br /> Cost/km = £13,621k<br /> <strong><br /> A-road (single)</strong></p> <p>Average based on costs of A737, A75 and A82 bypasses;</p> <p>Actual cost = £58,000,000<br /> Length (km) = 8.57<br /> Cost/km = £6800k</p> <p>I know nothing about building roads, but assume if you had to move a lot of earth to build cuttings / embankments or had bridges to build, then the cost goes up exponentially.</p> <p>The A82 Crianlarich bypass is 770m of single carriageway and comes in about £5,700k per km.</p> <p>Borders railway (upper estimate) comes in at £6,020k per km.</p> <p>Edinburgh tram the last time I calculated it was coming out at the eyewatering £60,625k / km (or put another way, it costs <u>£1 million to built 16.5 metres</u> of it) </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9259#post-96603 Fri, 11 Jan 2013 22:45:19 +0000 DaveC 96603@http://citycyclingedinburgh.info/bbpress/ <p>A freind is looking for the cost with references so he can point to it, per km of a dual carrageway. He can find some info which points to 5M/km (DFT circa2002 new build) but they have been quoted by the local authority 17M/km. If anyone has links this would be very helpfull.</p> <p>Cheers.</p> <p>Dave C </p>
