This photo is nothing like the reality of the long descent and climb up from the scary span with high sides to deter xtreme sports persons launching into the valley below
 Previous photos were of Hunter Street but since then several journeys have been along other highways.
The M1, Sydney to Newcastle secton would be the most ambitious, challenging, fastest and busiest in the land from what my travels have shown. Last Saturday afternoon the traffic was light.
Extensive roadworks meant kilometers of speed restrictions, in place to build extra lanes it is supposed. For one, the service centres this side of half way create problems. 
The last section closer to Newcastle is very boring until the TV transmitter on Mount Sugarloaf comes into view with relief that the home run is nigh.

 Hawkesbury or Brooklyn Bridges
