The caption at the bottom of the photograph indicates that this is the Martin's Creek Viaduct of the New Line, DL&WRR. It is a smaller version of the Tunkhannock Viaduct. Construction began in 1912 and ended in 1914. It is also known as the Kingsley Bridge, located at Kingsley, PA. It spans Route 11 and Martin's Creek. Coordinates: 41°44'38.70"N 75°45'9.60"W

Thanks for illuminating the fine print, technogeo. We will add a note to the record.

Hornibrook Bridge is a heritage-listed mostly-demolished road bridge on the Hornibrook Highway over Hays Inlet at Bramble Bay from Brighton, the City of Brisbane to Clontarf, Moreton Bay Region, Queensland, Australia. It was designed by Manuel Hornibrook and built from 1932 to 1935 by Manuel Hornibrook. It was added to the Queensland Heritage Register on 7 October 1994.[2] Handsome art-deco concrete abutment arches frame the entry and exit approaches. Construction of the bridge was important for the growth of the Redcliffe City peninsula and made the commute to Brisbane shorter and quicker, increasing population growth and the number of visitors to the seaside location. The bridge was known colloquially by the locals as the "Humpity Bump" because the road surface of the bridge was so buckled. During king tides, waves would crash into (and sometimes onto) the bridge spraying the cars as they crossed. The Hornibrook Bridge was the first of three bridges to cross Bramble Bay. The second bridge is the publicly funded (non-tolled) Houghton Highway bridge, which was built with the intention of duplicating the crossing capacity of the two-lane Hornibrook Bridge in the 1970s, but the upgrading of the original Hornibrook Bridge was subsequently found to be uneconomic. The bridge closed to traffic in 1979 with the opening of the Houghton Highway, which had been intended to provide a duplicated crossing. The third bridge, the Ted Smout Memorial Bridge opened to traffic in July 2010, delivering the desired capacity increase and resulting in the demolition of the original Hornibrook Bridge, which had been used as a pedestrian and bicycle-only bridge since 1979. The Hornibrook Highway Bridge was constructed in the years 1932–1935, by the firm of M.R. Hornibrook. Conceived as a response to high unemployment during the Great Depression, it also represented an opportunity to end the isolation of the residents of the Redcliffe Peninsula. Work officially commenced on the project on 8 June 1932, but in its first eighteen months, progress was limited, due to a lack of financing. The entry portals at either end of the bridge were completed in early 1933. Continuing financial difficulties forced Hornibrook to attempt to re-finance the company to finish the work as planned by 1935. The major flotation was assisted by a £100,000 loan from the AMP Society, guaranteed by the Queensland Government. Work recommenced at a faster pace from July 1934. The portals were designed by architect John Beebe. Originally a Bendigo-based architect, Beebe moved to Queensland in 1916 and worked at the Queensland Works Department until 1926. He then moved into private practice in Brisbane until 1936. The Hornibrook Highway Bridge was a 2.685 kilometers (1.668 mi) long timber and concrete bridge that spanned Hays Inlet and Bramble Bay between Clontarf and Brighton, linking Sandgate to Redcliffe. It had identical rendered concrete portals at each end, and two rises along its length which permit small boats to pass underneath. The portals at each end (which still exist) are finely detailed monumental Art Deco structures comprising substantial pylons spanned by a deep spandrel facing landward, and more modestly detailed rectangular frames facing backward. The pylons have banded rusticated bases on concrete pedestals, with central slot windows with decorative grilles on three sides, surmounted by stepped vertical elements. The spandrel is also banded and has a rectangular central panel with the words "Hornibrook Highway" fashioned in raised brass lettering. The portals contain toll facilities, comprising a small office and strong room with a night safe at the base of the pylons at each end. Externally these rooms are framed by Art Deco relief patterns. On the approach to the bridge, the portals are preceded by smaller free-standing pylons on either side of the road. Source: en.wikipedia.org/wiki/Hornibrook_Bridge
