HALIFAX — The Nova Scotia government will take another two years to study options for rebuilding or replacing the A. Murray MacKay bridge, one of two bridges that span Halifax harbour.

Public Works Minister Fred Tilley says his department will hire a company to examine the business case for the project.

Tilley says options include refurbishing the existing structure, building a completely new bridge or digging a tunnel.

A 2021 study found that replacement would cost more than $1 billion.

The span, which opened in 1970, connects Halifax and Dartmouth and will come to the end of its useful life by 2040.

The new report is due back to the government by May of 2028.

This report by The Canadian Press was first published July 10, 2026.
