RICHMOND, Va. (WRIC) — The Boulevard Bridge in Richmond has been re-opened after police closed the bridge Sunday due to the winter weather.

Bridges generally get icy and freeze before roads do because, unlike roads, bridges do not have anything underneath to insulate them. Instead, cold air is able to pass unobstructed over the top and underneath of bridges, cooling them much faster.

The Richmond Metropolitan Transportation Authority said the Boulevard Bridge was closed by The Richmond Police Department on Sunday due to icy conditions, and was reopened Monday around 2 p.m.
