I remember a surprise car tyre lying in wait one night. It had been deliberately left in the dark between two light fittings. Thankfully I had my lights on but barely saw it in time.

I’ve heard a story that someone riding through once came across an indie movie being recorded and thought it was real. Not sure if that was true.

Good information for when I check out the tunnel.

The Waltham Underpass could be promoted as a unique urban tunnel experience for those who are contemplating riding some of our National Cycle Trails and wish to gain confidence in riding through tunnels. Safety tips – a strong light helps. Be aware that wearing photochromic lens may quickly impair your vision. Be prepared to dismount when entering or leaving the southern end; the hump is significant. The Wednesday Wheelies Bike Group ride through here on occasion; to date there have been no issues of note and there hasn’t been a rider yet who hasn’t left the area with a smile on their face and a story to share.

I know what it’s officially called, but it’s still technically a motorway…

As mentioned, I have ignored any bridge abutment underpasses where one side is open (there are quite a few along both motorway corridors). They certainly also vary in relative quality, although most of the newer ones aren’t too bad.

By Northern Motorway, are you referring to the Christchurch Northern Corridor?

There’s also the stream-side underpass of the CNC at the Kaputone Creek, near Fords road.
