The Network in Numbers

The Facilities That Connect the Region
The 2050 RTP’s Regional Multimodal Corridors Network identifies the roadways, railways, greenways, and waterways that support regional travel for people and goods, enabling stronger regional planning. Developing this network is part of the ongoing coordination between the region’s MPOs in Miami-Dade, Broward, and Palm Beach counties.
