Banning right hand turns may not be the only change made at North Interstate and Greeley, the scene of two bicycle crashes in two weeks.

The City may install bike sensors, additional signage and the bike lanes may be painted blue through the intersection, according to Commissioner Sam Adams.

"It's a complicated intersection," said Adams.

Within hours of Tuesday's crash, right turns onto Greeley from North Interstate were banned. As an alternative route, people can use Going Street or proceed further south on N. Interstate, turn around, and take a left onto Greeley.

Adams said it could take the city "a couple of weeks" to determine what permanent changes could be coming to the intersection.

Kgw.com spotted a woman making a right turn despite the numerous signs informing her of the ban.

While most motorists obeyed the new rule, not everyone thinks it's a good idea.

"I don't think it [the deadly crash] had anything to do with the guy turning right, I think it had to do with the bicyclist who was going too fast down the hill," said one driver at the intersection Wednesday afternoon.

The cyclist, identified as Siobhan Doyle, broke several bones, she told KGW.

"I remember seeing the front of a car, hit my back shoulder and I went onto the ground," Doyle said. "It is a dangerous spot and I'm lucky that I'm still here to talk about it."

Both the driver and Doyle had a green light. Neither was cited.

Two weeks ago, a Portland cyclist, Brett Jarolimek, died at the same intersection under similar circumstances.

North Intertstate and Greeley is one of 14 Portland intersections considered the most dangerous for bikers and therefore targeted for what are called "bike boxes."

The boxes give bicyclists an area in front of cars to safely wait for a red light to change. Cars are prohibited from turning right at those intersections while the light is red.

"I think it's a great idea, I don't want to be killed," said cyclist Lea Ellen Young.

Southeast 39th and Clinton is the only Portland intersection currently with a "bike box."

Commissioner Adams has been asking for input from the public on his recommendation to install the boxes in the selected intersections. He hoped to have them all installed by the end of the year. Each "bike box" would cost $4,000 to put in place.

Adams said most of the feedback he's heard has been in favor of the boxes, but he said some motorists have raised concerns about the "no right on red" aspect.

"I think that inconvenience is a small price for more safety," said Adams, "I don't think any automobile driver or truck driver wants to hit a bicyclist and have to live with that for the rest of their life."
