 SH-16 was not extended beyond Beggs until 1954, when it was extended east to US-62 and US-64.This section of gravel highway had a slight jog to the north, causing it to meet the U.S. highways at Jamesville, north of the present-day junction.The following year, SH-16 was extended even further east, passing through Muskogee via US-62, US-64, and US-69, and proceeding along its present-day alignment to Okay.
