Renton Junction

In 1915 When the Sunset Highway was opened, you departed Seattle and headed south on the Pacific Highway. When you reached Tukwila you would have taken Macadam Road to Renton Junction. The original bridge cross the Green River is almost in the same spot as the new bridge on Southcenter Blvd.

There was also an alternate route to that took you from Allentown on the Duwamish River South down Beacon Coal Mine Rd and Monster Rd to Renton Junction. I believe this was the earliest route in the late 1800's.

From the county maps the road from Renton Junction to the corner of  7th St. and Shattuck in downtown Renton was actually called the Pacific Highway connection. You can see the maps below. So if this is the case then the Original Sunset Highway began in Renton from 1915 until the 1930's.

By 1920 The highway was rerouted onto what is now Interurban Ave S.

Renton Junction was a busy place in those early days as it was where all the railroads and the Trolley passed close to each other due to the surrounding hills.

By the 1930's the Highway was rerouted again from downtown Renton and connected to Martin Luther King Jr. Way.
