You'll have to "Pardon our Dust" this week as our Shelby roads/streets projects keeps on churning. TODAY, Monday, Main Street is reduced to ONE LANE traffic while the Montana Department of Transportation does crack sealing. Tomorrow (Tuesday) & Wednesday, Oilfield Avenue will be reduced to ONE LANE traffic for more crack sealing. Also tomorrow & Wednesday, the viaduct will also be reduced to ONE LANE traffic because of repairing guardrails over the viaduct. In the meantime, work will continue out on Roosevelt Highway as the overlay project moves toward completion.
