History
The road began as the Palmer Road in the 1930s to reach the agricultural colony at Palmer. It was completed to Glennallen during World War II as part of a military road and base programme that also produced the Alaska Highway, and it was paved in the 1950s. It is named for Captain Edwin Glenn (1857 to 1926), who led an 1898 expedition to find an Alaska route to the Klondike gold fields.[1]
