The cities of Mountain View and Sunnyvale will each chip in for a $1.2 million feasibility study on a future bicycle and pedestrian under-crossing at Bernardo Avenue, which is roughly the border between the two cities.

Mountain View City Council voted unanimously on Dec. 12 to provide $575,000 for the study, which would extend an earlier planned tunnel under the railroad tracks that would have stopped short of a crossing at Central Expressway.

Sunnyvale initially planned for a tunnel under the railroad tracks that stopped short of a crossing at Central Expressway, but agreed to extend the study to include a crossing of Central Expressway for the benefit of cyclists and pedestrians — if Mountain View contributed almost half of the $1,157,000 study.

The cities would seek funds from Santa Clara County Measure B, the transportation sales tax that passed last year, to build the crossing.

The nearest crossings are South Mary Avenue in Sunnyvale and North Whisman Road. Mountain View has six crossings across the railroad tracks and Central Expressway.
