Midway announced Monday a major expansion for its mixed-use CityCentre project that will include two new office towers, a high-rise multifamily building and new shops and restaurants.

Through a partnership with LaSalle Investment Management, Midway is set to begin marketing the office component of a 6.4-acre extension that will bring the northern border of CityCentre to Interstate 1o. The new buildings, which will be leased by Colvill Office Properties, will include a total of 740,000 square feet.

In addition, a residential building, 22,400 square feet of retail space and a one-acre greenspace has been designed for the project.

The new office buildings, CityCentre Towers 1 and 2, will rise 16 stories and include nine levels of parking. Floor plates will average around 26,000 square feet.

A 13-story multifamily building with 270 units is set to include one-, two- and three-bedroom floor plans. The building will have a rooftop amenity deck with a swimming pool.
