Hertford Bridge, often called the Bridge of Sighs, is a skyway joining two parts of Hertford College over New College Lane in Oxford, England.

Its distinctive design makes it a city landmark.

There is a false legend saying that many decades ago, a survey of the health of students was taken, and as Hertford College's students were the heaviest, the college closed off the bridge to force them to take the stairs, giving them extra exercise.

[1] The bridge links together the Old and New Quadrangles of Hertford College (to the south and the north respectively), and much of its current architecture was designed by Sir Thomas Jackson.

The bridge is always open to members of the college, who can often be seen crossing it.
