Route HH Roundabout Construction at Dr. Russell Smith Way in Jasper

What is the need for this project?

There are two closely spaced intersections that need to be combined into one to improve safety and accommodate increased traffic from future development in the area.

Why a roundabout instead of keeping the traffic signals?

Signalized intersections have approximately 20-30 conflict points, or spots where vehicles could collide, roundabouts reduce that number to eight. Fewer conflict points, combined with slower speeds and calmer traffic, translate into as much as 76 percent fewer crashes.  Signals also increase the delay of the travelling public due to a signal's cycle time.  With a roundabout, an approaching vehicle does not have to come to a complete stop unless there is already a conflicting vehicle inside the roundabout’s circle.

Will there be a signed detour?

No, the intersection improvements will be made while allowing traffic to continue to flow. However, drivers can expect occasional lane closures, with traffic through the work zone controlled by flaggers. There will be inevitable delays and drivers are encouraged to find alternate routes to avoid the work zone.

Will I still be able to get to Mercy Hospital?

Yes, one of the first things the contractor will do is build a temporary access road to Mercy Hospital.

Will any property be impacted?

Right-of-way and construction easements were acquired from three parcels.
