Tasman Predawn

People familiar with spinning into work along Hobart's Intercity Cycleway before the dawn's early light will be familiar with this scene. The air is still, the river a millpond, the bridge reflected against the briney black.

I'm told I arrived at work with a silly grin. I certainly felt good.

The Tasman Bridge is part of the route on Day 1, option 1 and leads onto Riawena Rd. It's a good view from the top.

The photo isn't from this morning (it was this time last year), like I say, it's a common sight, but it's worth a publish. As are some Tasman Bridge facts as taken from the plaque at the westen end, too...

All very interesting, shame it's a crap link to the Eastern Shore. I don't mind crossing it for a recreational ride, but it used to be a real chore to commute across by bike. Really glad I don't live there anymore, especially on windy days! The ol' girl looks good, sets off the harbour nicely, but she's totally car-centric.
