glennallen started as a construction camp during the construction of the glenn highway during the world war ii era. it was named after two u.s. army explorers of the 19th century: captain edwin glenn and lieutenant henry t. allen. the highway was completed in 1945 and glennallen flourished as a small community. the economy grew with the construction of the pipeline in 1975-1977. however, the economy was hindered by the completion of the george parks highway which bypassed the community on its stretch from anchorage to fairbanks.
