In 1909, Drammen got the first trolleybus system in Scandinavia, the Drammen trolleybus. The lines ran until 1967. For many years the centre of Drammen suffered from heavy traffic. In 1970, Drammen Bridge with two lanes on European route E18 was built (expanded to four lanes in 2006) and in 1999 the opening of the Bragernes tunnel (Bragernestunnelen) diverted additional traffic away from the centre of the city.
