Work is now commencing on widening a stretch of the A3 Autobahn where it passes through the Bavarian city of Regensburg. The 15km section of the A3 will be widened from its present two lanes to three lanes. The project is costing €270 million and will be carried out on the section from the junction between the A3 and B8 at Rosenhof to the east of Regensburg and running 15km westwards, past the junction with the A93 Autobahn route that connects with the A9 and Munich to the south. This work is needed as the section of the A3 becomes highly congested at peak periods, leading to long traffic delays. The A3 carries a high percentage of truck traffic along this stretch and in either direction. The project is expected to take until 2024 to complete.
