The Grant County housing boom continues with the scheduled opening of the Gateway Apartment complex in Moses Lake. The 2-building complex at Patton Blvd. and State Route 17 has one bedroom and two bedroom units with detached covered parking included. Crews broke ground in March and leasing of the units will begin in the middle of the month. According to the developer this is the first phase of construction that’s expected to bring more than 200 apartments.
