Manteca, California – A significant overhaul to the phased construction of the 120 Bypass/Highway 99 connector is poised to open large areas of Southeast Manteca for substantial economic development, officials announced today. The revised plan prioritizes the completion of the Austin Road interchange, a key component previously relegated to a later, potentially unfunded phase.

Originally, the northbound on-ramp and southbound off-ramp at the Austin Road interchange were slated for temporary closure, with more complex “braided ramps” planned for a third phase. However, under the revised proposal, these ramps will be restored during the second phase, tentatively scheduled to begin in four years. This change is driven by the City of Manteca’s sustained advocacy for faster access to the area.
key Project Details
The centerpiece of the second phase involves adding a second transition lane from northbound Highway 99 to the westbound 120 Bypass, enhancing traffic flow. This includes restoring the two ramps on the north side of the Austin road interchange. A deceleration lane on southbound Highway 99 will also be added, mirroring a similar design used in Modesto. The southbound on-ramp will remain as is, while the off-ramp will curve to become the start of northbound Moffat Boulevard, ensuring a smooth transition.
| phase | Key Components | Estimated Timeline |
|---|---|---|
| Current | Second transition lane from eastbound 120 Bypass to southbound Highway 99 | Ongoing |
| Second Phase | Full Austin Road interchange, second transition lane from northbound Highway 99 to westbound 120 Bypass | starting in 4 years (tentative) |
| original Third Phase | Braided ramps at Austin road interchange | 10+ years (potentially unfunded) |
Economic Impact and Funding challenges
Mayor Gary Singh emphasized that the project’s acceleration will unlock the full potential of the 1,080-acre Austin Road Business Park and surrounding land earmarked for employment centers. The park, initially attracting interest from major firms in 2010, was hampered by the limitations of the existing interchange.
The updated second phase is estimated to cost approximately $80 million, with roughly $50 million already identified. To bridge the gap, the city is exploring the creation of a community facilities district, leveraging future development to fund the remaining portion.
Did you Know? The original plan for the Raymus Parkway interchange, considered before the current project, was estimated to cost almost $90 million in 2010 and involved significant highway realignment and bridge construction.
Regional Transportation Benefits
Officials state the revised approach prevents potential traffic issues as Southeast Manteca expands and acknowledges that the vast majority of Manteca commuters travel west toward Lathrop, Tracy, and the Bay Area for work. Without the completed ramps, residents would be forced to use more distant on-ramps, diminishing the interchange’s usefulness.
Pro Tip: Stay updated on project developments through the San Joaquin Council of Governments website for potential traffic advisories and construction updates.
The San Joaquin Council of Governments is overseeing the project and adapting to challenges, such as a recent setback caused by Union Pacific Railroad’s restrictions on bridge support placement.
Long-Term Implications for Infrastructure Development
This project highlights a growing trend in infrastructure planning – prioritizing adaptability and phased development. The shift towards completing critical components sooner, even if it means higher upfront costs, can unlock significant economic benefits and prevent long-term congestion. It demonstrates the increasing collaboration between local governments and transportation agencies to address regional needs effectively. According to a recent report by the American Society of Civil Engineers, proactive infrastructure investments yield a return of $2.78 for every $1 spent, showcasing the long-term value of projects like this one.American Society of Civil Engineers

Full Interchange Complete: Change of Austin Road into Modern Traffic Hub
Understanding the Austin Road Interchange project
The recently completed full interchange at Austin Road marks a significant milestone in Austin’s ongoing infrastructure development. This project,focused on improving traffic flow and safety,has transformed a previously congested area into a modern transportation hub. The upgrade addresses years of increasing traffic volume due to Austin’s rapid population growth and economic expansion.Key areas of betterment include redesigned ramps, wider lanes, and the implementation of advanced traffic management systems. This isn’t just about easing commutes; its about supporting the city’s continued growth and ensuring efficient movement of goods and people.
Key Features of the New Interchange
The revamped Austin Road interchange boasts several key features designed to optimize traffic flow and enhance safety:
Direct Connect Ramps: Eliminating weaving sections by providing direct connections between major roadways. This reduces congestion and the potential for accidents.
Wider Lanes & shoulders: Increased lane widths and the addition of shoulders provide more space for vehicles and emergency access.
Improved signage & Lighting: Enhanced visibility through updated signage and brighter,more efficient lighting systems.
Advanced Traffic Signal Timing: Smart traffic signals that adjust timing based on real-time traffic conditions, minimizing delays.
Dedicated Bike Lanes & Pedestrian Walkways: prioritizing multi-modal transportation with dedicated lanes and safe pedestrian access.
Stormwater Management System: An upgraded drainage system to mitigate flooding risks during heavy rainfall.
Impact on Commute Times & Traffic Patterns
The completion of the interchange is already demonstrating positive impacts on commute times. Initial data suggests a reduction in peak-hour travel times by as much as 20-30% in affected areas.
here’s a breakdown of expected changes:
- Reduced Congestion: The direct connect ramps and wider lanes considerably reduce bottlenecks.
- smoother Traffic Flow: optimized signal timing and improved roadway geometry contribute to a more consistent traffic flow.
- Decreased Accident Rates: Enhanced safety features, like wider lanes and improved visibility, aim to lower the number of accidents.
- Better Access to Local Businesses: Easier access to businesses along Austin Road, perhaps boosting local economic activity.
- Shift in Traffic Patterns: Some minor adjustments to traffic patterns may be observed as drivers adapt to the new interchange layout.
Construction Phases & Timeline
The Austin Road interchange project was executed in several phases over a period of approximately three years.
Phase 1 (2022): initial site readiness, utility relocation, and preliminary roadway widening.
Phase 2 (2023): Construction of the main interchange structure, including bridge supports and ramps. This phase involved significant traffic detours.
Phase 3 (Early 2024 – Mid 2025): paving, installation of traffic signals, signage, and lighting.
Phase 4 (late 2025): Final landscaping, safety inspections, and project completion.
Throughout the construction process, the Texas Department of Transportation (TxDOT) provided regular updates to the public through its website, social media channels, and community meetings.
