Website City of Jefferson

Jefferson is a city in Marion County, Oregon, United States. It is part of the larger Salem area. In 2020, about 3,327 people lived there. The city sits on the right side of the Santiam River between Salem and Albany. You can find it along Oregon Route 164 and near Interstate 5.

History of Jefferson

The first name for this area was Conser's Ferry. This name came from Jacob S. Conser, who was a pioneer on the Oregon Trail in 1848. He started a ferry service across the Santiam River in 1851. Conser also helped create nearby communities like Syracuse and Santiam City. These places were about 2 miles (3.2 km) downstream from where Jefferson is now.

Later, a school called the Jefferson Institute was built in the area. Because of this school, the community eventually adopted the name Jefferson. The Jefferson post office opened in 1861. Its name changed from Syracuse, which had previously been Santiam City.

An important old building in Jefferson is the Jacob Conser House. It was added to the National Register of Historic Places (NRHP) in 1974. This means it is a special historical building. It even served as the city's library until 2018. The bridge over the Santiam River, which is part of Oregon Route 164, was designed by a famous engineer named Conde McCullough. It is named in Jacob Conser's honor. The Jefferson Methodist Church was also added to the NRHP in 1980.

In 2017, some changes happened in the city's leadership. Voters decided to remove the mayor, and three city council members also left. This was due to disagreements about adding new land to the city.
