The San Juan Bridge is the major viaduct across the San Juan Water Reservoir, along the South Luzon Expressway (SLEX). A new bridge, called the San Juan Bridge No. 1, was constructed between the two existing bridges of the north and southbound lanes of the expressway. The bridge was constructed without closing the north and southbound bridges from traffic.
The San Juan Bridge No. 2 was constructed after completion of San Juan Bridge No. 1. The old southbound bridge was demolished and a new bridge was constructed. During its construction, traffic was diverted over bridge no. 1. Called the San Juan Bridge TR-2H Stage 2A in the contract, it is the first of the two bridges in the Stage 2 contract.
The San Juan Bridge No. 3 is the northbound portion of the whole San Juan Bridge. It was constructed after completion of bridge no. 2. During its construction, traffic was diverted over bridges no. 1 and no. 2. The same as bridge no. 2, bridge no. 3 was constructed by demolishing the old northbound bridge and the new bridge was constructed. After construction, all three bridges were connected by pouring the closure gaps with one-day concrete.
Roads at the north and south portion of the bridge were constructed.
