The US 101 northbound off-ramp at Hermosillo Road will remain closed for the next two months as part of the US Highway 101 Butterfly Lane Pedestrian Undercrossing Project.  This closure is necessary to allow for the relocation of ramp lighting and a pile driving operation which will occur for six days beginning Monday, Dec. 13.  Travelers headed northbound may exit US 101 at Hot Springs Road.

A long-term 24/7 closure of the Butterfly Lane Pedestrian Undercrossing continues and will include reconstructing the stairs and adding new ramps for wheelchair and mobility scooter access at each end of the Undercrossing that are compliant with the Americans with Disabilities Act (ADA).  The railroad crossing at the south side of the Undercrossing will include a new walkway, handrails and crossing arms with visual and audio signals. 

Pedestrians and Cyclists are encouraged to use the Olive Mill Road Overcrossing as a detour during this construction project.  Notices will be posted to advise all travelers about the temporary closure of this undercrossing.

The mural inside the Undercrossing will be maintained as part of this project.  The contractor for this $3.7 million project is C.A. Rasmussen Inc. of Valencia, CA.  This project is expected to be complete in the Summer of 2022.

Caltrans reminds motorists to move over and slow down when driving through highway construction zones.

Anyone taking the bus to the summer Music Academy of the West performances and all day class schedules uses this underpass. Encouraging safe, clean, attractive and accessible public transit use is a good thing.

Considerably more than “10+ people a day” use the tunnel. I lived for 20 years on Butterfly Lane and speak from experience. I have been and continue to maintain the mural by painting over the vandalism when I can get into town to do so, and depending on the time of day, there are typically dozens of pedestrians per hour while I’m down there painting. You may or may not have a righteous claim about East Carrillo, but you clearly have no idea about the volume of pedestrian traffic in the Butterfly tunnel.

$3.7M would be better spent on the more dangerous roadway.

Obviously you have not walked, ran or bicycled on E. Carrillo under the 101.

BTW, nice paintings, too bad about the vandalism(s).

That's all nice for a pedestrian undercrossing that may serve10+- people a day.. but what about the East Cabrillo undercrossing (Under 101) that serves at least 500-1000 cars and 100+ people/cyclists a day? Now THAT is very VERY dangerous, and no way safe for Pedestrians and Cyclists and forget people with disabilities.
Maybe the peeps that set roadway and pedestrian construction priorities should thunk. - just sayin
