European route E134 (Norwegian: Europavei 134) is a European highway that crosses Norway starting at Haugesund Airport, Karmøy near the city of Haugesund on the west coast, heading over Haukeli, passing the city of Drammen, and ending in Vassum on the east side of the Oslofjord Tunnel.

[1] With the highest point at 1,085 metres (3,560 ft) above sea level, the road is sensitive to snow conditions and foul weather during the winter season, during which the mountainous sections, especially near Haukelifjell skiing center, may be closed in short periods.

Due to local wishes and steadily increasing of the road standard during the 1990s, it again received European route status, with the number E134.

The route has many tunnels, especially in the mountainous sections in the central and western parts, especially along the Åkrafjorden, where is passes the Langfossen waterfall.

In 2018 E134 was extended by 40 kilometres (25 mi), to include the Oslofjord Tunnel, letting it end at Vassum at the European route E6 in Frogn municipality in Eastern Norway.
