Description:
The Jefferson and Irvington lines, each older lines dating back to 1890, were merged in 1914 by PRL&P in 1914. The line ran from an western terminus at S.W. Jefferson and 18th to 5th, then north across the Steel Bridge. From there it jogged east on Holladay and Multnomah to 15th, where it continued north to its western terminus at Prescott.
The entire Jefferson leg was discontinued in 1933, and the line was once again the "Irvington" line. This, in turn, was converted to autobus in 1938.
