At the corner of North Winooski and Riverside Avenues, McAllister caught the road crew in action on October 1, 1932. The large machine in the center of the photograph is a concrete mixer preparing the mixture that would soon be poured over the steel grid to the left of the machine. One man is seen probably pouring a bag of cement onto the gravel and sand, which would be flipped up into the mixer and combined with water in a rotating drum before being dumped out onto the web of reinforcing steel bars to cure. The concrete base being applied here, and all along North Winooski Avenue, is seven inches in thickness, and will support a two-inch-thick asphalt surface.[1]

In between the concrete mixer and dump truck can be seen the CPS Filling Station at the corner of North Winooski and Riverside Avenues. The station was owned by Charles P. Smith, who was also the owner of a local Ford and Lincoln dealer.[2] The station carried Tidewater Oil, or Tydol, petroleum products.

To the left of the concrete mixer is the office for the Burlington Rapid Transit and Vermont Transit Co., which owned the entire corner of the block other than the filling station.[3]
