Skurubron, Concrete arch bridge in Nacka Municipality, Sweden.

Skurubron is a pair of parallel concrete arch bridges over the Skurusundet strait in Nacka Municipality. The older bridge, completed in 1915, has a main arch spanning 72 metres and rising 32 metres above the water, with side arches of 49 metres. The newer bridge, opened in 2023, is a continuous beam bridge with six spans on five Y-shaped piers carrying two steel box girders.

A floating bridge built around 1830 by Wermdö Brobyggnadsbolag, engineered by Immanuel Nobel, father of Alfred Nobel, first crossed Skurusundet at the old ferry site. The reinforced-concrete arch bridge designed by Axel Björkman with Tor Kempe opened on 18 October 1915, inaugurated by King Gustav V; at 284 m long with a 72 m main arch it was then Northern Europe's largest concrete bridge. A parallel bridge was added in 1953–1957.

The name Skurubron comes from Skurusundet, the strait it crosses, which also separates Södermanland from Uppland. Since 2023 the name belongs to the new beam bridge, while the two 1915 and 1957 arch spans are called Gamla Skurubron. The old crossing is to become a separate walking and cycling route, with the other half used by local traffic.

The new Skurubron carries länsväg 222 (Värmdöleden) and has a toll of four kronor since 1 October 2023, while the adjacent Gamla Skurubron is toll-free. The old bridge's Stockholm-bound half is being converted into a separate walking and cycling route across the sound, with the other half kept for local traffic. The whole project, including the old bridge's rebuild, is due for completion in 2025.

The 1915 arch was built on a temporary artificial island of sand and timber piles dredged into the six-to-ten-metre-deep channel, carrying a fan-shaped scaffold rated for 2,000 tonnes. When the formwork was removed eight weeks after casting, the mid-span sank only 4 millimetres. The island was then dredged away again.
