Right between (1 ) St Isaac’s Cathedral and (2) City Hall there is (3 ) bridge that is very hard to see. It is as wide as (4 ) adjacent Isaakievskaya Square.

To the disappointment of (8 ) people of (9 ) St Petersburg (10) Blue Bridge was not accepted as (11) Widest Bridge in (12) World by (13)_____ Guinness Book of (14) Records. The reason for this is unknown (probably there is no reason at all). If you find (15) wider bridge elsewhere in (16)______ world, please, let us know. (17) Blue Bridge was designed by architect V. I.

(19) lower part of (20) Blue Bridge is still painted blue.
