The intersection of OR 213 and Toliver Road was controlled by stop signs and has a high rate of crashes. A roundabout will improve safety by reducing sharp turns while also accommodating the type of traffic that uses it, including large vehicles like trucks, buses and agricultural equipment.
In 2018, ODOT conducted a Road Safety Audit which studied the safety concerns and travel through the intersection and identified potential solutions. Through this audit and work with local agencies and engineers, it was determined a roundabout will bring the greatest safety benefits.
In addition, we installed new lighting at the intersection.

At the intersection of Toliver Road
Cost and Funding
$9.6M including funding from the City of Molalla.
The intersection of OR 213 and Toliver Road has a high crash rate, within the top 10 percent of all highway segments in the state. Between 2007 and the end of 2016, there were 38 crashes and 83 percent of crashes resulted in injury. Constructing a roundabout will improve safety for travelers while still allowing turning movements.
What is a roundabout?
A roundabout is a type of circular intersection that uses yield signs to control traffic entering the intersection. Roundabouts are designed with curved entrances to reduce speeds and to reduce high-speed, head-on, right-angle and turning crashes, which improves safety.
Why not install a traffic signal?
While a traffic signal may facilitate all the directions of traffic and turns, installing new traffic signals can result in an increase in rear-end crashes. In rural areas, new traffic signals are associated with a 77 percent reduction in angle crashes, but also a 58 percent increase in rear-end crashes, which can be severe and fatal in high-speed areas.
Traffic signals do not address speeds at an intersection − roundabouts do reduce speeds. Often drivers accelerate through an intersection to try to make it through before the signal turns red, which is dangerous.
A roundabout was found to facilitate all directions of traffic and turning movements while bringing the greatest safety benefits, including reducing speeds into the community.

Can trucks/buses/farm equipment use a roundabout?
Yes! The roundabout will be designed to accommodate the types of vehicles that currently use this intersection, including school buses, farm equipment and trucks.
If you are concerned about a piece of equipment fitting through the roundabout, please contact the project team.
