Boston makes impressive use of granite for many things. There were granite curbs everywhere, and granite bollards:

This low curb lining the pedestrian sidewalk on a recently redone street has generous use of granite for some pavers and low curbs. Note the little post to mark the indent for the bench. Also envy the lush planting in the boulevard.

In addition to this little granite posts, big ones were used for street signs in a few places.

Granite curb marked with rust from the snow plow blade. This was in a park and ride lot for the LRT/subway.

Here is granite milled into a curb for the end of planter strip separating aisles of parking in the park and ride lot.

In Ottawa, granite curbs are used on Parliament Hill and parts of Confederation Boulevard.
