MNS Transportation Wins the Cabrillo Bridge Project Over Mission Creek!

Congratulations to the MNS team for their win on the Cabrillo Boulevard Bridge Replacement Project! The project is located right down the street from our Santa Barbara office next to Stearn’s Wharf.


History of Cabrillo Boulevard Bridge

This historic bridge was originally built in 1913, but additional reconstruction was performed in 1927 and 1977. This bridge was built on one of the busiest roads in Santa Barbara because it is right next to the iconic Stearn’s Wharf pier which brings in a lot of tourism into Santa Barbara.
One of the City’s objectives is to preserve the architectural integrity of the aesthetic features reflecting these periods of history that have long contributed to the atmosphere of the waterfront community in the region. Therefore, both the structural and architectural features of the replacement project have been carefully planned to include features that are consistent with the historic nature of this highly used public facility.

MNS and Cabrillo Boulevard Bridge

Replacement of the Cabrillo Boulevard Bridge and reconstruction of Mission Creek both upstream and downstream of the bridge represents a significant milestone in completion of Santa Barbara’s Lower Mission Creek Flood Control Project. MNS CM transportation team has recently replaced the nearby Chapala Street Bridge and Ortega Street Bridge over Mission Creek. This project along with other bridge projects of similar scope proved that MNS is the best choice for the project.

Here’s the project team:


The bridge replacement project will be constructed in three stages and includes demolishing the existing bridge and adjacent channel walls as well as the complete reconstruction with an improved bridge structure, channel walls, embankments, and tidal habitat. The team must reroute the traffic throughout the duration of the project in stages.Here’s a visual layout of the project.


MNS CM Transportation Department Wins US 101/Los Osos Valley Road Interchange Improvements Project!

Congratulations to the MNS team for their win on the Los Osos Valley Road Interchange Improvement!  The US 101/Los Osos Valley Road (LOVR) Interchange Improvements Project represents a vital improvement for traffic capacity and circulation in southern San Luis Obispo.

The current three-lane Los Osos Valley Road interchange was built in 1962. As the City and population has grown, the interchange is in need of structural repair and widening to improve travel conditions and accessibility to a variety of transportation types. The purpose of the US 101/LOVR Interchange Improvements project is to maximize the efficiency of LOVR and the US 101/LOVR Interchange in order to improve functionality and accommodate the growing amount of traffic. LOVR serves as the only primary east/west corridor between South Higuera Street and the community of Los Osos.

MNS and US 101/Los Osos Valley Road

The current interchange consists of a modified diamond configuration with a loop on-ramp to northbound US 101 in the southeast quadrant. The existing bridge is a four-span, 330’ long by 55’ wide structure with a non-conforming sidewalk along the north side. Westbound lanes consist of a single lane from South Higuera Street to the bridge, where two lanes continue across the bridge toward the Irish Hills and shopping centers. East bound traffic consists of a single lane from Calle Joaquin, across the bridge and becoming two lanes approaching the entrances to Los Verdes Park 1 and Park 2 and terminating at South Higuera Street.The current bridge, which has an average of 26,300 vehicles that travel each day, has one sidewalk. This project will consist of widening Los Osos Valley Road to a continuous four lane roadway between the entrances of the Los Verdes Parks and the existing four-lane roadway west of Calle Joaquin. The new bridge will be a four-span structure approximately 370’ in length and 40’-6” in width. Embankments in excess of 20’ in height will be constructed for the widened road and bridge approaches. Other improvements, such as widened sidewalks and bike lanes, will also be included. The project also provides for beautification and environmental sustainability with the construction of permanent erosion protection, architectural treatment of the concrete barriers, ornamental lighting fixtures, new and modified drainage systems, and creek restoration. Storm Water Pollution Control is another important element of the project; the US 101/LOVR Interchange Improvements Project has been determined as Risk Level 2. MNS has certified QSP and QSD staff to ensure the project’s compliance with the approved SWPPP and Water Pollution Control Board 401 permit.

This project is planned to be completed within 18 months.

Pitkins Curve: Transportation Construction Management

MNS Transportation Division, Construction Management Team: Spotlight Project

Hazardous Rock-slides on One of California’s Landmark Motorways

The Pitkins Curve and Rain Rocks Shed project, located between Monterey and Cambria on California State Route 1 (Highway 1) was a major undertaking aimed at making a dangerous section of the scenic state highway safer for motorists.

The Pitkins Curve area of Highway 1 is part of an active landslide­; rock slides are a fact of life here, rather than an unusual occurrence. Its geological composition is particularly unstable. Rock slides repeatedly closed the original road and presented a significant danger to motorists.

Foreseeing that Pitkins Curve would continue to be a major safety issue and an access impediment for the millions of tourists traveling through the area each year, not to mention a major maintenance and cost issue, the California Department of Transportation (Caltrans) developed an innovative solution to the problem.
