The boundary of the community which is sized as much as 2.78 sq mi borders on the north to the village of Kreimbach-Kaulbach, Wörsbach on the northeast, Schallodenbach on the east, Mehlbach on the southeast, Hirschhorn/Pfalz on the south and Sulzbachtal and Frankelbach on the west.

The roads inside the village are named in alphabetical order: Am Berg, Am Hanhgraben, Am Rutzenbach, Am Waldhof, Auf den Wingerten, Bachstraße, Bahnhofstraße, Bornweg, Dietenbachstraße, Hauptstraße, Hebelstraße, Hohlstraße, Im Holzgraben, Im Kirschgarten, Kirchweg, Schneidersäcker und Wörsbacher Straße.

The train station of Olsbrücken is placed a few metres outside of the local boundaries, so the ground there belongs to the village of Frankelbach.

The name "Auf den Wingerten" reminds that in past there must have been a vineyard inside the boundaries of the village.

The Palatinate has one of the mildest climates of Germany, as it is situated west of the river Rhine and influenced by maritime western winds.

In the Middle Ages around the year 1250 there is a certificate available that speaks about a man called Ludovicus (Ludwig) who came from Alsbrücken.

In 1635, 15 km away from Olsbrücken at Kaiserslautern, that was occupied by Spanish troops that time, forces of mostly Croatian origin slaughtered at least 90% of the inhabitants.

Olsbrücken belonged to the Departement du Mont Tonnere and the administrative responsibility was delegated to the city of Otterberg.

During the 19th century a lot of people from Olsbrücken and the surrounding villages emigrated to the United States of America, because poverty was a part of their everyday life.

The remarkable Protestant church was built in the late 19th century according to plans from the architect Ludwig Levy.
