REDMOND, WA — A new off-ramp along SR 520 in the Overlake area will open Thursday, but there will be construction delays coming up this week to prepare for the opening.

On Thursday, the eastbound off-ramp to Northeast 40th and Northeast 51st streets will be separated to reduce backups. Here's what to expect this week as far as construction before the new ramp opens:

Monday - Wednesday: The SR 520 HOV lane between Northeast 40 and Northeast 51st streets will be closed from 9 p.m. to 5 a.m. each night.
