The A2 in the canton of Uri, the Gotthard motorway, is one of Europe’s major transit routes. The motorway, which was built in the 1970s, is being gradually refurbished. This work is expected to increase safety for road users and make driving more comfortable. In Uri this refurbishment will also provide relief for communities living near the motorway.

Quieter surfaces  

The traffic routes in the Reusstal are confined to a narrow area, giving rise to a high level of noise pollution in the area. The refurbishment of the Gotthard motorway involves laying road surfaces that significantly reduce noise emissions. Noise barriers have been installed in the few places where the new road surfaces have not been possible, providing residents with some respite.

Motorway provides a flood bypass channel

An unusual method of flood protection: The Reusstal is sometimes affected by severe floods. In the event of severe flooding the motorway will be closed and used as a flood bypass channel if the riverbed of the Reuss is no longer able to absorb the sheer volume of water.

New method

The run-off from motorways must be treated before it can be discharged into any body of water. Basler & Hofmann have developed a new method for treating the run-off on the A2. The water will pass through tanks which are equipped with highly efficient chemical filters. Unlike conventional ground filters, this equipment requires significantly less space. This is a powerful solution for a narrow valley.
