Inspired by Hitler's autobahns, one of Northern Ireland's busiest roads - the Sydenham Bypass - turns 65 today


The Sydenham Bypass, now one of Northern Ireland’s busiest routes, has become a pensioner.

Although only a short stretch of road – less than three miles long – it was pioneering for its era, being built to near-motorway standard and unveiled weeks after the first long stretch of the M1 in England was opened.
But the Sydenham Bypass would have beaten the M1 to completion by almost 20 years, if not for Adolf Hitler – the German dictator who in fact inspired the road. The bypass’s Scottish engineer R Dundas Duncan had visited Germany in 1937 as part of a British delegation to inspect Adolf Hitler’s admired new autobahns, which revolutionised long distance motoring.
The key design feature in such roads was the lack of any gaps or crossing points in the central reservation, thus entirely separating inbound and outbound vehicles. To this day such roads. known as expressways, have the lowest death tolls because they eliminate two of the most dangerous manoeuvres on the road, turning right and overtaking in the face of oncoming traffic.

Finally, at its opening on November 23, 1959, the prime minister of Northern Ireland Lord Brookeborough and other officials sat in covered stands to see the new road, which would alleviate congestion on the nearby Newtownards Road. The News Letter reported: "The opening of the road, which has special paths for cyclists, was as the Governor (Lord Wakehurst) described it, a new era in road development."
The dignitaries then drove to Stormont where "the government gave a luncheon".
The road is now one of the busiest in the province and there are long-term plans to widen it to three lanes. Wesley Johnston, who runs a website about roads, says: "Although most who use it every day do not realise its significance, the Sydenham Bypass is remarkable in being the first, modern dual-carriageway constructed in Northern Ireland."

A bridge over the Lagan, completed in 1995, was the only section of the M3 to be constructed. The first motorway in Ulster, the M1 to Lisburn, opened two-and-a-half years later in mid-1962. Access to the Sydenham Bypass was improved in 1966 with the new Bridge End Flyover and Queen Elizabeth Bridge.
Mr Johnston said: "The Sydenham Bypass now carries almost 60,000 vehicles per day, and has stood the test of time remarkably well." His roads website is at http://www.wesleyjohnston.com /roads/
