other roads with double lane links or bridges needing urgent replacement. These bridges then were not being fully utilized due to minimal volume of traffic while in three instances, single lane bridges were constructed in double lane road links.
Records also revealed that apparently, the general criteria to give priority to bridges lying along higher category roads in terms of functional classification and with higher traffic volume was not observed.
Construction of a number of double lane bridges under the President’s Bridge Program was prioritized in places with basically no road links or with mere single lane roads over other roads with double lane links or bridges needing urgent replacement.
Out of 176 double lane bridges inspected by the team, 82 or 47% were constructed in sites without road links appropriate to the size of the bridge constructed while only single lane bridges were constructed in three (3) sites with double lane road links. The two lane bridges constructed were then not being fully utilized due to minimal volume of traffic while vehicle movements in the three (3) double lane roads with single lane bridges were likewise affected. While one of the selection criteria under the program is availability of funds for the construction of road links within two years upon bridge construction, compliance with this criterion was apparently not also monitored.
The two lane roads with installed single lane bridges follow:

While the needs of these areas for bridges could not be discounted, such could be addressed by constructing only single lane bridges which was noted also to be part of the project. The Tulay ng Pangulo sa Countrywide covered construction of 80 single lane bridges. It was even noted that the road links in areas with installed single lane bridges were better off than the road links in some areas with installed two lane bridges as depicted on these pictures:

It was further noted that while construction of a number of bridges were prioritized in areas without apparent immediate need, inspection disclosed that a number of bridges along developed barangay roads need immediate replacement and/or conversion to permanent ones. The principle that bridges for replacement or for conversion to permanent ones are considered more urgent and shall be given higher priority over bridges for repair/rehabilitation or for construction was not also
observed. The needs to replace the following bridges along local roads were already apparent:

Bridges with lower scores were given priority in the construction as illustrated in the following cases:

The team also noted that in a number of instances, the constructed bridges in Regions I, VII and XI were not included in the masterplan/inventory list of local bridges.
Since selection criteria were intended to identify priority bridges, non compliance with these criteria would result in selection of bridges with practically no urgent needs of construction/replacement.
