ferries on Lake Washington. The first completed railroad on the Eastside was the Lake Washington Belt Line, opened from Renton to Woodinville in late 1904 by the Northern Pacific Railway. It was intended to allow freight to bypass Seattle's congested railyards and was also served by passenger trains. The area's first log roads had been built in the early 1890s and were expanded across the region by the beginning of the 20th century, including predcessors to I-405. A north–south road between Kirkland and modern-day Bellevue was completed in 1908 and gradually extended south to Renton and north to Bothell. The road, named Lake Washington Boulevard, was fully paved by 1932 and designated by the state legislature as part of Secondary State Highway 2A (SSH 2A) in 1937. SSH 2A traveled north from US 10 in Renton to Primary State Highway 2 (PSH 2) in Bothell, continuing onward to US 99 in Everett. Three Tree Point Road, which connected Burien to Renton, was designated as SSH 1L. The Bothell–Everett section of SSH 2A was later removed from the state highway system in 1943. Planning for a series of upgrades to transform SSH 2A into a suitable bypass of US 99 around Seattle began in the late 1940s. A plan announced in 1947 would use federal funds to build a new two-lane road between Bellevue and Woodinville, supplementing another road to Kennydale that was already under construction. Additional right-of-way would be acquired to allow for expansion to four lanes at a later date. Following a survey by the state highway department, a route generally following 116th Avenue Northeast was chosen in 1949; plans also called for a limited-access highway with several cloverleaf interchanges dependent on available funding. A section of the new highway between Kennydale and Bellevue began construction in February 1947 and was completed the following year. The East Pacific Highway Association, formed to plan a major highway to the east of US 99 from Tenino to the Canadian border, lobbied the state legislature for funding to complete the link between Renton and Woodinville. The state government approved plans for the Eastside highway in 1952 as part of its limited-access highway network and allocated funds to begin acquisition of right-of-way along the corridor. The federal Bureau of Public Roads included the Eastside bypass of Seattle in its 1955 recommendation for a national system of Interstate routes. The system was approved by
