Page "Nova Scotia Highway 102" Paragraph 3

The entire highway is a divided 4-lane freeway, with the exception of a 5-lane ( 3 lanes northbound ) section between the Highway 118 interchange at Miller Lake and the Halifax International Airport at Enfield.

This 3-lane northbound section is not a result of particularly high traffic volumes but rather it is a relic of the previous configuration of this section of Highway 102.

Previously the section from Fall River to near Enfield was a three-lane undivided section, including a centre passing lane favouring northbound traffic.

When the highway was twinned the three lanes were left in place for northbound traffic.

Portions of Highway 102 south of the Halifax International Airport pass through several microclimates and are notorious for frequent variations in visibility due to fog caused by elevation changes.
