HALIFAX, N. S. – Last December, the Nova Scotia Department of Transportation and Infrastructure Renewal (DTIR) announced an accelerated bridge review program, to begin Feb. 4, for the designation of B-train routes across the province.
More precisely, the program will determine which roads can accommodate six-axle semis at 47,500 kg GVWs.
However, since the bridge analyses will be valid for 62,500 kg GVW B-trains, the DoT will only have to analyze road features such as the horizontal and vertical curvatures, lane widths and passing possibilities to determine their suitability for Btrains.
In practice, the main users of designated B-train routes are six-axle semis running at 47,500 kg GVW.
That is heavier than the 41,500 kg permitted for these semis on routes without the Btrain designation, but equal to the GVW of a B-train without the rear trailer.
“A number of companies asked the DTIR to designate routes as B-train routes so they could run semis at 47,500 kg.,” says Doug Stonehouse, program manager, weights and dimensions policy, Nova Scotia Department of Transportation and Infrastructure Renewal. The program completion date is unknown.
