The A 1 an A 2 wur first planned in the 1920s. The interchynge atween the twa (Kamener Kreuz) wis ane o the first cloverleaf interchynges in Germany, opened in 1937. A 1 aroond the soothren side o Hamburg wis opened in 1962, includin a bridge athort the Elbe. This bypass connectit the existin Autobahn segments on baith sides o the ceety.
Northren extension an the Fehmarnbelt airt
The A 1 is still bein extendit north, wi an extension tae Heiligenhafen-North planned for openin in 2011. A treaty haes been entered atween Germany an Denmark for the construction o a fixed airt athort the Fehmarnbelt tae Denmark, tae be finished in 2018. As pairt o the treaty, Germany will also extend the A 1 tae Puttgarden, wi the exception o the Fehmarn Soond Bridge atween the mainland an Fehmarn island, which will remain in its current state.
The Vulkaneifel interchynge wi the A 48, just sooth o the 36 km lang gap in the A 1 sooth o Cologne, wis built in the 1970s. This interchynge wis finally utilized in the present century, though only for local traffic as the A1 is bein extended past Kelberg. Plans hae been made tae complete the remainin 21 km ower the Land borders atween North Rhine-Westphalia an Rhineland-Palatinate, This will tak till 2018 afore it is ready. Till then, through traffic atween the twa sections uises the A 48 an the A 61 an various regional roads.
