Protesters blocked off a main thoroughfare to the Bahrain Financial Harbour, a key business district in the Gulf Arab banking centre.
Authorities failed to dislodge the thousands of protesters blocking King Faisal Highway in Manama, the capital.
About two miles (about three kilometers) away, police also moved on the Pearl Square protest camp in the largest effort to clear the area since the demonstrations, inspired by the uprisings in Tunisia and Egypt, started in mid-February. Another rally at a university Sunday also reportedly descended into clashes with police.
Thousands of youths ran across the King Faisal Highway as police backed away in the face of hundreds of protesters who had gathered near the Pearl roundabout, the focal point of weeks of demonstrations on the small Gulf island.
Traffic was stalled for miles (kilometers), and police fired tear gas and used heavy vehicles to try to move the protesters and dismantle the barriers they had set up.
