1:48 pm OSP is advising motorists there is just under a 20-minute delay at the scene of a semi-truck accident on I-5 northbound just north of Ashland. Crews are working to clear the wreckage.

1:41 p.m. A semi truck is blocking one lane of northbound Interstate 5 just north of Ashland after it collided with a road grader at about 10 a.m. today, police say.

Traffic is moving around the wreck site, which is north of Ashland's northern freeway exit.

The grader is overturned in a ditch at the side of the road, and its driver was transported to Providence Medford Medical Center with minor injuries, said Oregon State Police trooper Brandon Boice.

Boice said the grader driver was in the freeway's slow lane headed north on the freeway. The commercial truck was moving from the fast lane to the slow lane when it struck the grader.

Local drivers advised to avoid Interstate 5 at S. Medford interchange starting March 16

South Medford project narrows I-5 to one lane in each direction

MEDFORD - Drivers in south Medford are being advised to avoid Interstate 5 starting Monday, March 16 as the highway narrows down to a single lane of traffic in each direction.

"We know this will be a major inconvenience for everyone," said ODOT Project Manager Joe Thomas. "There will be traffic delays. How far and how long the delays last will depend on local drivers."

Nearly one half of the 48,000 vehicles between the two Medford interchanges consist of local traffic.

The six-week project will rebuild the I-5 roadbed with two feet of aggregate material and topping that with nine inches of new asphalt.
Work will proceed with two shifts, 22 hours a day. ODOT worked with the contractor to reduce the number of days of single lane traffic.

The single-lane work zone provides the contractor adequate space in the confined area between the Medford Viaduct and the Bear Creek bridges.

New southbound off-ramp opens first

The new southbound off-ramp will open prior to the I-5 lane closures, allowing drivers to travel in either direction atop the new interchange overpass.

"We expect the new off-ramp will help traffic during the lane closures," Thomas said.

The $70 million South Medford Interchange project began in 2006. A joint venture with the City of Medford, the project is designed to improve safety and congestion.

The centerpiece of the project is construction of a new interchange 1,900 feet south of the existing Barnett Road exit (exit 27).

The new interchange design is called a single point urban interchange (SPUI), which can handle large volume of traffic. The SPUI is located close to Bear Creek, so additional bridges are needed to accommodate the retaining walls for the on- and off-ramps.
