The population of the Tri-Cities region grew substantially in the late 20th century, causing increased traffic congestion on the urban sections of SR 240. A $58 million highway widening program was completed in 2007 by WSDOT, expanding SR 240 to six lanes between Stevens Drive and Columbia Center Boulevard. The Yakima River Bridge was demolished in 2004 and replaced by a set of two bridges carrying three lanes each, as well as a multi-use bicycle and pedestrian trail. The western portion of the Columbia River Trail interchange at the Richland Wye was converted into a roundabout that opened to traffic in June 2007. A separate $16 million project completed in November 2009 converted the cloverleaf interchange at US 395 into a dogbone interchange with two roundabouts to improve safety and traffic flow. Due to remaining congestion issues on the Bypass Highway, WSDOT is considering several strategies to increase capacity, including reversible lanes, high-occupancy vehicle lanes, and opening the shoulder to traffic during peak periods. Long-term plans from the City of Richland propose the conversion of the Bypass into a full freeway with interchanges and right-in/right-out access to replace existing intersections.
