Part IV of my daily bike commute to work series. Here is partIII and links to earlier ptI&ptII.

2 of 5 miles. The Tay Road Bridge has a central walkway sandwiched between the two main trafic carridgeways, for bikes and pedestrians. Access to this central walkway on the south side of the bridge, is via this underpass, also blipped here from the other direction.
