The national highway 490 (abbreviation: W 490 ) was until 31 December 1974, a German federal highway in the eastern Lower Saxony . It was built to enable a better connection between Braunschweig and the federal highway 7 .



Around 1940 there was a plan for a Reichsautobahn Evestorf (branch of the Hamburg-Hanover line) - southwest of Uelzen - Braunschweig - Bad Gandersheim (confluence with the Hanover-Kassel line). With the comprehensive investigation into the further construction of the Hamburg – Hanover – Kassel line at the beginning of the 1950s, the route of today's A 7 was relocated from the west of Hanover to the area east of the Lower Saxony state capital. At the same time, it was not expected that the plan for a second motorway via Braunschweig would be taken up again. The project initially disappeared in the drawer.

Planning and construction

Nevertheless, work was carried out on improving the connection between the Braunschweig-Salzgitter area and the new federal motorway 7. As a first component of this plan, a direct connection between Üfingen and Salzgitter-Engelnstedt was built in the 1950s, on which the B 490 was later laid. The Rüningen – Üfingen line was added by 1962. However, it was the construction of a two-lane state road that was not free of intersections, but bypassed built-up areas. The Wartjenstedt – A 7 and Salzgitter-Lebenstedt-Nord – Salzgitter-Lebenstedt-Süd routes were in the planning stage. By the mid-1960s, the entire route between the A 7 at what is now the Salzgitter motorway junction and the B 248 south of Braunschweig was completed and designated as the B 490. The federal road between Üfingen and Braunschweig was already built with four lanes. This was followed by the four-lane expansion between Üfingen and west of Salzgitter-Lebenstedt-Süd, which was available to traffic from 1966. However, not all intersections were removed between Üfingen and Salzgitter-Lebenstedt-Nord, so that a renovation had to be carried out here in the second half of the 1970s. In 1968, the four-lane expansion between the junction Baddeckstedt and Salzgitter-Lebenstedt-Süd was finally completed, although the route had to be relocated later between Westerlinde and Salzgitter-Lichtenberg; the Braunschweig – Derneburg railway line at that time was also built over.


With the restructuring of the federal motorway network, which was introduced with effect from January 1, 1975, many individual projects - including the B 490 - became a new line under the uniform name of " Federal Motorway 39 ". The B 490, which was already like a motorway anyway , was upgraded to its full length.


There is nothing left of the B 490 itself. A few roads that are quite straight for the region, including the K 40 in Salzgitter, part of the L 474 and the K 76 in the Wolfenbüttel district, bear witness to its first course . They run parallel to the later course, which today forms the A 39. In this section, this is partly not yet on the motorway standard: In some places the hard shoulder is still missing today , which was not required for the construction as a federal highway and was not added during the upgrade. Some bridges in particular only offer space for a motorway-like road.
