Monday, June 11 will see the opening of a downtown transportation feature years in the making. A new roundabout near the Central Library will open with Main, Navarro and San Pedro as feeder streets.

Roundabouts aren't that common in South Texas, so San Antonio Transportation and Capital Improvements provided this video with tips for navigating traffic.

According to a spokesperson with San Antonio TCI, roundabouts offer continuous traffic flow with no lights that calm traffic. The lower speeds of roundabouts can reduce the risk of crashes, and the spaces for bicyclists and pedestrians are wider and clearly marked.

The new downtown roundabout will eventually allow traffic to flow through five streets, with no signal lights. Construction on the roundabout will continue through July 2018. Until then, N. Main and Camden will remain closed. The roundabout is a $6 million dollar project funded through the 2012 voter-approved bond program.
