PROPOSED REHABILITATION OF QUEZON BRIDGE AND APPROACHES
IN MANILA
OUTLINE FRAMEWORK
1.0 PROJECT INFORMATION
1.1
Project Description and Significance
The Quezon Bridge provides a critical link to vehicles traveling to and from inner Manila.
However, the structural condition of the Quezon Bridge needs to be checked based on the
current design codes so that it would be seismic resistant and safe to carry the present live
load. Moreover, the bridge was damaged by fire and also at risk from damage due to
earthquake forces.
As such, the proposed structural assessment and rehabilitation of Quezon Bridge is one of the
traffic mitigation projects proposed for immediate implementation by the National Capital
Region (NCR). The project involves the repair and rehabilitation of the superstructure to
conform to the current code, and strengthening/retrofitting of existing substructure. If
necessary, the bridge shall likewise retain its original configuration conforming to the National
Heritage Act of 2009, preserving a historical structure built 50 years and older within a historical
site. The existing bridge approaches will be repaired to suit the existing horizontal alignment.
Existing Bridge Condition
Quezon Bridge was constructed in 1939 and is one (1) of seventeen (17) bridges crossing Pasig
River on the Quiapo side connecting Quezon Boulevard to Lawton on the Ermita side in the city
of Manila.
Quezon Bridge is a combination of Arch Steel Bridge with a length of 106.40 meters and a PSC
Girder Bridge with a length of 142.80 meters with approaches of 197.80 meters long on both
approaches. The bridge has a total length of 447.00 meters and with a total width of 22.50
meters including sidewalks and islands, with two (2) traffic lanes on each direction. The main
structural members below the deck are very seriously affected by corrosion, particularly the
main lower chord members and the connections of longitudinal stringers and transverse girders
near expansion joints and along the lower chords. Due to fire incident, the slab soffit was
heavily damaged at Quiapo side including the structural members of the bridge.
