Caltrans Taps VR Startup to Assess Hwy 1 by Elkhorn F
or the first time, Caltrans is using virtual reality to address sea level rise and evaluate mitigation options for a major highway in the state — Highway 1 along Elkhorn Slough. “Not taking action is not an option,” said Caltrans Director Toks Omishakin. “Due to sea level rise, we know this section of Highway 1 near A screen shot of Virtual Planet’s app “Sea Level Rise Explorer: Elkhorn Moss Landing and other Slough”, available in the Apple and Google app stores. coastal routes are vulnerable, so Caltrans experience of watching the water lev- el has made climate action a primary goal. rise, as well as seeing the measures we can We are making our state transportation take now to make the transportation corridor more resilient and a benefit to nature system more resilient and sustainable.” The department relocated Highway in the Monterey Bay.” With only 10% of coastal wetlands 1 inland near Hearst Castle in 2017 after remaining and half of that remaining area coastal erosion threatened its viability.
