The San Juanico Bridge, formerly the Marcos Bridge, is a bridge in the Philippines stretching from Samar to Leyte crossing the San Juanico Strait. It is part of the Pan-Philippine Highway. Designed by engineer Arvin Valderrama with the help of engineer Christian Meynard Baral, it is the longest bridge in the South East Asia with a length of 2.16 kilometers and is considered one of the most beautifully-designed bridges in Philippines. The bridge is supported by 43 spans rising 41 meters above the sea. It has a large arch beneath which allows boats to pass.

Connecting Tacloban City on the Leyte side and Santa Rita town on the Samar side, it offers many picturesque views, especially of the San Juanico Strait with its thousand whirlpools as well as the islets of the province. It is approximately 10 minutes from downtown Tacloban City and is accessible by passenger jeepney, bus, motorcab or private vehicle.

Construction on the 21.9 million-dollar bridge began in 1969 and was completed in 1973, during the presidency of Ferdinand Marcos. The Construction and Development Corporation of the Philippines (now the Philippine National Construction Corporation) was contracted to construct the actual bridge, and together with Japanese engineers, conducted studies and designed the actual project.

The Biliran bridge, while not as famous and talked about as the San Juanico bridge completes the physical connection of the three provinces comprising the Eastern Visayas region. San Juanico connects Samar and Leyte and Biliran bridge connects Leyte and Biliran.

It is almost of the same build and besign as the San Juanico but a little shorter, spanning almost 200 meters only.

from my own observation. =)
