Work includes construction of a two-way-left turn lane along Excelsior Middle School frontage and a left turn pocket at the intersection of Byron Highway with Byer Road. Additional improvements include pavement striping, installing drainage facilities, applying a slurry seal, creating a concrete median, an asphalt walkway and relocating existing rapid flashing beacon systems, as well as installation of speed feedback signs.
