NSTIR has provided notice that they plan to open the Dunns loop / Trunk 4 Detour as early as Monday June 27th or Tuesday June 28th. If your commute includes this stretch, please use caution and leave yourself some extra time to reach your destination!
From NSTIR staff:
The geometry of the road at the East Curve will be improved with Better superelevation than when opened previously in summer 2014. The superelevation is the amount that the outer edge of a curve is banked higher than the inner part (sometimes called the cross slope).
NSTIR will be extending the 60km/hr zone further West, and installing Portable Variable Message Boards with “Sharp Curve, Drive With Care” message warning and Speed Radar signs advising motorists of their speed as they approach the curves. There will be added Chevron Signs and curve warning signs for the Eastern Curve. NSTIR did consider rumble strips, but proximity to residences would be too close to allow their use.
In addition the work related to opening the detour will take place at night to avoid long delays while constructing the transitions.
Although rumble strips are not going in, there appears to be significant effort to ensure safety.
