Stage 1 of the I-805 North Express Lanes Project constructed one carpool lane in each direction in the median of I-805 from just north of SR-52 to just north of Mira Mesa Boulevard and a south-facing Direct Access Ramp at Carroll Canyon Road. 
The construction cost for Stage 1 is about $86 million and is funded with state, federal and local sources, including the Proposition 1B State – Local Partnership Program and TransNet Extension funds.
