A 1,600-metre (one mile) section of the Stresemannstrasse highway in the Altona district will be closed to older diesel trucks from May 31.

Meanwhile both diesel-powered trucks and cars that do not meet the latest Euro 6 emissions standards will be banned from a 580-metre stretch of another major and heavily polluted road, the Max-Brauer-Allee.
