Multimodal Mobility Improvements - Segment 4 - Project
Multimodal Mobility Improvements - Segment 4 - Project
Caltrans is proposing to construct curb ramps complying with the current Americans with Disabilities Act (ADA) standards, a sidewalk/bike path (Class I), which is a shared-use path, a traffic signal on 77th Street East, flashing beacons, along with drainage improvements. This proposal will be placed on State Route 138 (SR-138), from Avenue T in the City of Palmdale to the junction with State Route 18 (SR-18) in Llano, which was designed as a Corridor. This Corridor was divided into several segments, each of which is a separate project. The Multimodal Mobility Improvement, Segment 4, Project is one of the 14 segments programmed. Originally, the Corridor improvements were intended to provide additional highway capacity on Pearblossom Highway. However, this project segment will only provide multimodal improvements and enhance safety on Pearblossom Highway.

Overview
The Multimodal Mobility Improvement, Segment No. 4, Project (EA 28600) is approximately 1.2 miles in length and is in the community of Littlerock. The limits of this segment are from 70th Street East to 0.1 mile east of 77th Street East, PM 53.1 to PM 54.3. This segment’s project scope will provide multimodal transportation access and enhance safety.
Project Status: Plans, Specifications, and Estimate (PS&E) Phase
This project is currently undergoing design review and construction review to be completed by June 29, 2026. The project team is evaluating class 1 bike path per Traffic Safety's request and Right of Way requirements.
A Class I Bike Path was proposed on August 2, 2023. Right of Way appraisal maps were completed in April 2023 based on the assumption that pavement work was included in the project scope. Segment 4 project limits include pavement areas identified in green, yellow, and orange. As a result, the design needs to be adjusted using the existing topo.
Additional Right of Way studies are required to evaluate the proposed Class I Bike Path and associated sidewalk improvements. The amount of required Right of Way acquisition may change as the design progresses.
Utility Relocation
The following utility relocations are currently anticipated due to the proposed no-widening alternative:
34 Southern California Edison (SCE) poles
8 fire hydrants
1 water meter
6 water valves
2 telephone cabinets
3 guy posts
7 electroliers
Approximately 3,000 feet of water line
Approximately 600 feet of gas line
Approximately 4,000 feet of AT&T telephone lines
The extent of utility relocation and parcel acquisition may change as studies for the proposed Class I Bike Path and sidewalk improvements continue.
Schedule Update
Project postmiles were corrected on January 3, 2026. A Project Change Request (PCR) will be submitted to move the project schedule from Fiscal Year 2026–27 to Fiscal Year 2027–28. This adjustment will allow sufficient time for Right of Way activities to be completed and support the project's goal of reaching construction contract acceptance by June 2030.
