Some people call it the Pasadena Freeway, others refer to it as the 110. Officially, it’s the Arroyo Seco Parkway. Whatever you call it, this 86-year-old roadway—L.A.’s first freeway—is destined for some road work and changes, but not for a couple years.
The $43 million Arroyo Seco Parkway Upgrades Project is scheduled to begin construction in 2028 and be completed by the end of 2029, according to Katy Macek, a spokesperson for Caltrans. Although some people may have noticed construction recently along the parkway at Avenue 43, it’s not part of this project, but is a harbinger of things to come.
Work will be done on three sections of the highway in Northeast Los Angeles:

The most complex part of the project is replacing the bridge between the 110 and the 5. That involves building a wider right shoulder, and upgrading signs, crash cushions and safety lighting.
The other two parts of the project both involve replacing bridge railings with post-and-beam see-through concrete barriers.
Caltrans hopes to have the approval for the project by the end of this year, Macek said.
