Traffic just got a little more congested at Central Oregon Community College. Construction on the new science building is causing part of "Loop Road" to be closed. Ron Paradis with the college says the closure started today. “What that means is students, faculty and visitors will have only one way to get to upper campus through the serpentine lot. Which is the first turn to the right when you come up College Way.” The road will be closed for the next 18 months, while construction continues.
