Bear River Bridge

The Bear River Bridge looking east in the 1960s.

Mile 12.86 on the Yarmouth Subdivision. Just east of the Bear River station.

At 1640 feet in length, this was the largest bridge on the DAR, and the second longest bridge in Nova Scotia.[1] It crossed the wide tidal mouth of the Bear River. This bridge, along with the Clementsport Bridge and The Joggins Bridge, were the key challenges in the "missing link" between the Annapolis Royal and Digby. The bridge was completed by the federal government in 1890 allowing the Windsor and Annapolis Railway and the Western Counties Railway to connect and form the Dominion Atlantic Railway. There were two versions of the bridge, the first wooden bridge built in 1890 and its steel replacement built slightly to the north starting in 1912 and completed by 1913.[2] and [3] Both contained a large swing span on the far west end of the bridge to allow sailing vessels passage to the busy timber wharves in the village of Bear River several miles upriver.The bridge was abandoned in 1990 and demolished in 2012. The bridge was documented before the demolition in 2010 by the archaeological firm Davis MacIntyre & Associates.[4]

Specifications

Structure: 1640 feet long in its final configuration[5], it included from east to west:

  • One 39-foot Deck Plate Girder Span
  • Six 100-foot Deck Plate Girder spans
  • Three 156 feet 9¼ inches Deck Truss spans
  • One 144 feet 6 inches Deck Truss Swing span
  • One 156 feet 9¼ inches Deck Truss span
  • One 103 feet 3 inches Deck Plate Girder span
  • One 50 feet 1 inch Deck Plate Girder span.

(Span lengths taken from a 1918 profile drawing at File:YA-13.62 Bear River.jpg.)

A hidden feature on the swing bridge were the underwater wooden pilings driven on both sides of the approach to protect the swing span piers from collision damage.

A 32 foot "pepperpot" wooden lighthouse was built beside the west end of the bridge in 1905.[6]

The Clarke Brothers Pulp Mill was built on the east end of the bridge in 1919 but went out of business in 1923. The mill's brick and concrete structure was used for other purposes and remained beside the tracks until the late 1980s.
