Route

The A418 is a medium-distance A road which has been truncated over time.

Section 1:Wheatley - Aylesbury

M40 junction 8A

It starts its journey at the Sworford trumpet interchange at Wheatley on the A40. It has the unusual feature of having two junctions with the M40 within 1/2 mile: the end of the A40 spur here and junction 8A shortly afterwards. Also it is part of a multiplex with the A40 here, the A418 taking numbering priority. Prior to the building of the Wheatley bypass in 1962-63 it ended right before the abutment of the old Oxford - Princes Risborough railway line bridge. The disused line will follow us alongside until we reach Thame. The old section of road can still be walked down, behind a set of gates, just after the new junction with the A40.

About 1/2 mile after the main M40 junction the A40 turns off to the right on a new-build road for non-motorway traffic, built as the original slip road was closed when the M40 extension was opened. We then head into Tiddington, a small village that has been asking for a bypass for many years to no avail. After Tiddington the road gently twists and turns its way for 5 miles towards Thame. We arrive at Thame at the roundabout junction for the A329 (former B4013), which now ends its journey from Bracknell way. Before the bypass was built the A418 made its way through the small market town, with its narrow streets via two TOTSOs to emerge at the other side. The Thame bypass was opened in 1980. It seems to be over-engineered but this was due to plans for a major route from the East coast to the M40 and on to Swindon that has yet to come to fruition.

At the roundabout junction with the A4129, B4011 and B4045 the road reverts to its previous standard, slightly narrow and twisty. We are now heading off towards Aylesbury. At the top of a small hill a right turn heads off to the town of Haddenham; the A418 appears to be a bypass of the town but actually it isn't. We work our way through Stone and then after a sharp 90-degree left turn we head into the outskirts of Aylesbury.

Section 2:Aylesbury - Wing

Roundabout on the edge of Aylesbury

After multiplexing around Aylesbury town centre on the A41, the A418 continues on the town's ring road for a short distance, to a roundabout with the A413. Turning left at the next roundabout and right at the mini-roundabout after that, the A418 rejoins its old route. Aylesbury almost seamlessly becomes the village of Bierton, and then, other than the small hamlet of Rowsham, the road isn't built up at all until Wing. At Wing, the road sharply turns left, then right again, causing a bottleneck on the Aylesbury - Milton Keynes route. Plans to bypass the village have existed for a great many years, very nearly getting built in the late-1980s, then causing great controversy in 1991, when the design specification was significantly increased, due to being part of a major new build trunk route (that fell flat with the Wing bypass plans). Wing, incidentally, was proposed at one time to be the site of London's third airport, so it is possible that the A418 would have been diverted and/or heavily upgraded to serve that. At the north end of Wing, the A418 terminates on the Linslade Southern bypass (formerly A505)/Western bypass (A4146) junction.

Bucks CC had plans to rebuild the A418 between Aylesbury and Linslade as an at-grade D2. From north of the ring road, instead of turning left, the A418 would take an upgraded Stocklake out of Aylesbury, to a roundabout, where a link to Woodlands Roundabout on the A41 would head south, and the A418 turn north to meet the current road just north of Bierton. A short online section would be upgraded, before a Rowsham bypass that heads to Wingrave Cross Roads, where a Wing northern bypass takes traffic and puts it on the Linslade Western bypass just north of the village.

Section 3: Linslade - Bedford

Historically, the A418 headed through Linslade and Leighton Buzzard, heading alongside the Light Railway for a while, before meeting the A5 north of Heath and Reach. From there it went through Woburn and Ridgmont to Ampthill, before turning north and heading to Bedford. Strangely the A418 didn't get a junction with the M1, that honour going to the B557 about a mile to the northwest, which meant that that road got more and more important (it's now the A421), and the A418s less and less, eventually leading to the downgrading and renumbering of the A418 north of the A5 (unclassified south of Woburn, A4012 south of the former B559, A507 to Ampthill, B530 to Bedford). The Linslade Southern bypass (A505) meant the section through Leighton Buzzard and Linslade was also downgraded.
