Within Overlake, SR 520 turns north and passes through several office parks, including the headquarters campus of Microsoft and the Nintendo of America branch office. To serve exits at Northeast 40th Street and Northeast 51st Street, SR 520 gains a set of collector–distributor lanes, separated from other lanes by a concrete barrier. The freeway crosses the Sammamish River and turns east, passing to the south of the Redmond Town Center mall and Bear Creek and to the north of Marymoor Park. East of downtown Redmond, SR 520 intersects SR 202 and terminates; the road continues north as Avondale Road towards Cottage Lake. Portions of the corridor from Montlake to Downtown Redmond are also paralleled by a shared-use trail for bicycles and pedestrians.
