Why is the A5 dead straight from Marble Arch to Elstree?

  1. it’s a chunk of Roman road (Watling Street, which ran from Dover to Chester via London), and they did like nice straight lines, insofar as the landscape let them.

    The London-Holyhead road it forms part of was the first road built to improve communications between London and Dublin after the 1800 Act of Union, and because it was a mail and stagecoach route it is built to be as flat and straight as possible, for the horses.

  2. The steering wheel was invented a surprisingly long time after the regular rolling wheel. So in those days they just pointed in the direction they wanted to go and couldn’t turn until they got there. That’s why trains were so popular. They could still turn without a steering wheel.

  3. Romans. It’s the site of the original Gauntlet, traditionally 7 miles long but truncated for the ITV show Gladiators in the 1990s.

  4. Because it’s built on top of Watling Street, the old Roman road.

  5. It’s almost entirely straight (a couple of turns but it gets back onto the same course) from Park Street Railway Station near St Albans right through to Marble Arch. I’ve thought about walking it later this year, maybe in the summer.

  6. The standard of driving on that specific road is so bad that planners decided against complicating it by adding corners.

  7. It’s great to cycle. Straight from all the way up near st Albans in fact!

  8. I’d be more intrigued about the 1 hr 20 to go 10 miles….

  9. I once cycled it on my way from SE London to East Lancashire. God it’s a boring road. I turned off it near Nuneaton and boy was I glad

  10. Same reason most of the A1 (or at least the old Roman road that runs next to large sections of it) is pin straight where it can be. Ermine street and all that. I used to live 200m from a huge section of it, it is ridiculously straight. They did a good job when setting it out. It’s even on a six foot high + ridge.

  11. Take another look at the map of London. You will see lots of Roman roads. Kingsland Road (A10) for example, runs through Dalston and basically runs straight all the way to Tottenham, wiggles a bit but carries on as the main road to Cambridge.

  12. It has some sort curves but not noticeable when you’re zoomed out.

  13. If you follow the A5 onto the A5183 it leads to a place called London Gate, in St Albans that is Masonry foundations of an ancient Roman city gate at the archaeological site of Verulamium.
