The Hulme Arch Bridge in Hulme, Manchester, England, supports Stretford Road as it passes over Princess Road, and is located at grid referenceSJ838968. The construction of the bridge formed part of the regeneration of the Hulme district of Manchester, both by re-establishing the former route of Stretford Road, which had been cut into two halves by the construction of Princess Road in 1969, and by providing a local landmark. The location was previously occupied by a footbridge.
The bridge consists of a deck supported by cables from a single arch that spans the bridge diagonally. The design was selected in June 1995, with construction running between May 1996 and April 1997. It was opened on 10 May 1997 by Alex Ferguson.
History
Stretford Road was divided into two halves in 1969 by the construction of Princess Road.[2] A footbridge was subsequently constructed, crossing Princess Road at the same place as the road previously ran.[3] As part of the regeneration of the Hulme district, it was decided to construct a new bridge to rejoin the two sections of the road, and also to provide a local landmark.[2]
The bridge consists of a 50 metres (160 ft) bridge deck of three 17 by 17 m (56 by 56 ft) steel and concrete decking segments covered with tarmac.[4] The deck is supported by twenty-two 51 mm diameter[5] spiral steel cables originating from both sides of a 25 metres (82 ft) high arch. The parabolic arch is made of six prefabricated trapezoid steel box sections, and spans the bridge diagonally.[4] The bridge is illuminated at night.[5][2]
The arch varies between 1.6 metres (5.2 ft) wide by 1.5 metres (4.9 ft) deep at the bases to 3 metres (9.8 ft) wide and 0.7 metres (2.3 ft) deep at the top.[7] It is supported by a pair of 8.5 by 6.5 by 5.5 m (27.9 by 21.3 by 18 ft) concrete blocks, which bear most of the weight of the bridge. The deck is supported by piled abutments, which incorporate areas for bearing and expansion joint inspection and maintenance. The arch is kept in shape by a number of internal stiffeners and diaphragms, with the top section filled with concrete. To minimise internal rust, the lower sections of the arch were coated with a vapour corrosion inhibitor, with portholes with removable covers inserted into the arch so that the inside could have additional coats applied in the future.[2]
Construction
The three sections of decking were assembled on the broad central reservation of Princess Road, and were craned into position over a weekend when Princess Road was closed.[4] The decking was temporarily supported by trestles until the arch was ready.[2] The six sections of the arch were welded together on site into two halves before being lifted into position during a second weekend.[4] The cables were connected on the third weekend.[2] The bridge was formally opened on 10 May 1997 by Alex Ferguson[2] in a ceremony including the Lord Mayor of Manchester and Tony Wilson. The ceremony was concluded by them being driven over the bridge in a Rolls-Royce Silver Ghost, and was followed by a street festival.[8]
The bridge has been described by the structural engineers as "a perfect example of how imaginative design combined with leading-edge engineering technology can be used to create a landmark structure which captures the public's imagination."[2] In 1997 the bridge was shortlisted for the British Construction Civil Engineering Award. In 1998, the bridge received a Royal Institute of British Architects Award for Architecture; a British Constructional Steelwork Association Structural Steel Design Award Commendation; a Civic Trust Award Commendation, and Institute of Civil Engineers Merit Award.[5]
