January 20:

Jeff Morrison has provided some research-related updates to kick off this site's 28th year online:

IA 2 (I): The first paved segment dated back to 1916, per the Atlantic News-Telegraph of December 1, 1916. It was also diagonalized between Monroe and Otley in 1924 and straightened between Atlantic and Wiota in 1926.
IA 2 and US 61 previously followed Avenue E in Fort Madison before moving to Business US 61's present route along Avenue H sometime in 1952 per the Fort Madison Daily Democrat of August 25, 1952.
IA 3 (I): Two miles east of the Missouri River were paved in 1930, while the rest of the segment west of Sidney was paved in 1931.
IA 4 (I) and IA 12 originally ended at the Missouri state line; the alignment change south of Hamburg occurred in 1928 and was paved in 1931 before becoming US 275, per the Atchison County (MO) Mail of July 3, 1931.
IA 9: The former IA 86 (III) was originally part of IA 9, but the designation came two decades after IA 9 was relocated north of Fertile.
IA 10: The 1932 paving ended at present-day 160th Avenue east of Peterson.
IA 43 was paved inside Ringsted in 1939, with the remaining segment becoming bituminous after that.
IA 96 shifted north a mile between IA 14 and present-day C Avenue in the 1948 paving.
IA 327 followed 140th Street and 253rd Avenue.
IA 348 followed 13th Street in Carter Lake instead of 9th Street.
US 18 was paved from Dickens to present-day 260th Street in 1932, and paved from there to Spencer on its present alignment in 1933, per the Spencer Reporter of October 14, 1932.
US 20 was paved through Ida County in 1936, although the relocation was approved in 1935.
US 30: The 1928 paving excluded the north-south segment of US 30 through Logan and the Boyer River crossing; those were paved in 1930, according to the Harrison County Herald of September 25, 1930.
US 32: Overhead railroad crossings at West Liberty, Atalissa, and Wilton were paved in 1931 instead of 1930.
US 34: The 1929 paving east of Corning ended at present-day Orange Avenue instead of IA 49.
US 63: The 1930 paving through Jasper County was on a new alignment that paralleled the railroad tracks through Prairie City and Monroe.
US 71: Paving history from 1932 to 1941 was updated, particularly the last segment into Minnesota, which was completed in 1941 per the Spirit Lake Beacon.

Exit list update: The GrimesPlex is now signed at IA 141 exit 152.
