Week of Nov. 17:

Please use caution in the work zone and follow construction signage. Construction schedules are weather-dependent and subject to change.

Asphalt paving operations and travel impacts | Nov. 10 - 16

Starting as soon as Tuesday, Nov. 12. South Boulder Road will be reduced to one lane of alternating traffic, with flaggers, between Sir Galahad Drive and Malory Street while crews place asphalt pavement.

Crews will also pave Sir Galahad Drive and Malory Street at South Boulder Road. These streets will be closed in order to complete paving operations and will remain closed until the asphalt is ready for traffic. Both streets will not be closed at the same time to allow for alternate access. Please follow posted detour signs.

No Parking signs have been placed at Robin Hood Street and Avalon Avenue at South Boulder Road to prepare for paving operations this week.

Motorists should expect delays and traffic impacts at the intersection of 120th Street and South Boulder Road. Alternate travel routes are advised as delays of up to 15 minutes are expected.


Intermittent brief lane closures on South Boulder Road are expected over the next few months. The location of the lane closures will vary and travel delays are expected. Please allow extra time on your drive through the corridor or use alternative routes.

Paving operations on the north side of South Boulder Road are complete. Westbound traffic is on the north side of the orange median barriers, while eastbound traffic remains on the south side. The new configuration allows crews to complete the remaining work at the South Boulder Road and 120th Street intersection.

New Traffic Alignment on South Boulder Road




New Traffic Configuration on Eastbound South Boulder Road


As construction progresses, a new traffic pattern will begin starting Monday, Oct. 14. The new configuration allows crews to complete the remaining work at the South Boulder Road and 120th Street intersection. The new configuration will include the following changes:

  • Orange barrels will be placed at the intersection to protect the work zone and direct motorists traveling eastbound on South Boulder Road or southbound on 120th Street.
  • For eastbound South Boulder Road to southbound 120th Street: Motorists will stay to the right of the median barrels and yield to merge with southbound 120th Street traffic.
  • For eastbound South Boulder Road to northbound 120th Street: Motorists will keep to the left of the median barrels.
  • The intersection will function as a 4-way stop.


South Boulder Road Multimodal Improvement Project Update – April 2023
(Versión en español abajo)

City Council and staff share the community’s frustration with the South Boulder Road Multimodal Improvement Project and have taken recent actions to move the Project forward. Progress resulting from a Work Change Directive and an agreement with the contractor, Castle Rock Construction Company, has re-activated construction operations within the corridor.

The contractor has agreed to have the next phase of construction on the south side of South Boulder Road (SBR) completed by September 30, 2023. Work activity will then move to the north side of SBR.

Storm Sewer Work Directive
On March 9, 2023, the City issued a Work Change Directive requiring the contractor to perform certain storm sewer work that was required due to a design change.

Agreement with the Contractor
On March 16, 2023, the City and the contractor reached an agreement on cost and schedule issues related to the Project. This agreement is subject to formal City Council approval, which is expected to occur on April 4, 2023.

In the agreement, among other things, the contractor agreed the following work will be completed by Sept. 30, 2023:

  • All work along the south side of SBR necessary to shift traffic from the north side of SBR to the south side of SBR.
  • This includes all work necessary to rework and install the redesigned storm sewer line along the south side of SBR.
  • This also includes all work relating to the multiuse path, curb and gutter, asphalt base layer, and preliminary paving along the south side of SBR.

Water line plans
The City determined it is in its and residents’ best interest to replace the existing 50-year-old water line that runs under SBR at the same time the other work is being performed in the area. This added scope will improve the integrity and longevity of the infrastructure. On March 13, 2023 the City received plans from the designer for a new water line. The contractor has agreed to take all reasonable efforts to provide a proposal to the City by March 31, 2023 for the additional cost and additional time to perform the replacement water line work.

Next steps
Once work on the south side of SBR is completed in September 2023, construction efforts will move to focus on the replacement of the water line on the north side of the road and other work necessary to complete the Project.

City Council and staff would like to thank the community for your patience with the ongoing disruption along South Boulder Road. The City of Lafayette is committed to enhancing safety and multimodal travel for all users along this corridor and to relieve residents and commuters of the frustrating inconvenience this Project has caused. Since the Project began in early 2021, the City and crews have encountered many unexpected conflicts and delays. At this time, it is anticipated the entire Project will be substantially complete (normal traffic patterns will resume) by approximately mid-2024.

Actualización del Proyecto de Mejora Multimodal de South Boulder Road - abril 2023

El Concejo Municipal y el personal comparten la frustración de la comunidad con el Proyecto de Mejora Multimodal de South Boulder Road y han tomado medidas recientes para hacer avanzar el Proyecto. El progreso resultante de una Directiva de Cambio de Obra y un acuerdo con el contratista, Castle Rock Construction Company, ha reactivado las operaciones de construcción dentro del corredor.

El contratista ha acordado completar la siguiente fase de construcción a lo largo del lado sur de South Boulder Road (SBR) para el 30 de septiembre de 2023.

Directiva de trabajo del Alcantarillado Pluvial
El 9 de marzo, la Ciudad emitió una Directiva de Cambio de Trabajo que requiere que el contratista realice ciertos trabajos de alcantarillado pluvial que fueron requeridos debido a un cambio de diseño.

Acuerdo con el Contratista
El 16 de marzo, la Ciudad y el contratista llegaron a un acuerdo sobre el costo y cuestiones de calendario relacionadas con el Proyecto. Este acuerdo está sujeto a la aprobación formal del Concejo Municipal, que se espera que ocurra el 4 de abril.

En el acuerdo, entre otras cosas, el contratista acordó que el siguiente trabajo se completará el 30 de septiembre de 2023:

  • Todo el trabajo a lo largo del lado sur de SBR necesario para cambiar el tráfico desde el lado norte de SBR al lado sur de SBR.
  • Esto incluye todo el trabajo necesario para volver a trabajar e instalar la línea de alcantarillado pluvial rediseñada a lo largo del lado sur de SBR.
  • Esto también incluye todos los trabajos relacionados con el camino multiuso, bordillo y cuneta, capa de base de asfalto y pavimentación preliminar a lo largo del lado sur de SBR.

Planes de Línea de Agua
La Ciudad determinó que es en su mejor interés y de los residentes reemplazar la línea de agua existente de 50 años de antigüedad que corre bajo SBR al mismo tiempo que se realizan los demás trabajos en la zona. Este alcance adicional mejorará la integridad y la longevidad de la infraestructura. El 13 de marzo, la ciudad recibió planos del diseñador para una nueva línea de agua. El contratista ha acordado hacer todos los esfuerzos razonables para proporcionar una propuesta a la Ciudad antes del 31 de marzo por el costo adicional y tiempo adicional para realizar el trabajo de reemplazo de la línea de agua.

Próximos pasos
Una vez que el trabajo en el lado sur de la SBR se complete en septiembre de 2023, los esfuerzos de construcción se centrarán en la sustitución de la línea de agua en el lado norte y otros trabajos necesarios para completar el proyecto.

El Concejo Municipal y el personal quieren agradecer a la comunidad por su paciencia con la interrupción en curso a lo largo de South Boulder Road. La Ciudad de Lafayette se ha comprometido a mejorar la seguridad y los viajes multimodales para todos los usuarios a lo largo de este corredor y aliviar a los residentes y a los viajeros de los frustrantes inconvenientes que este Proyecto ha causado. Desde que el Proyecto comenzó a principios de 2021, la Ciudad y los equipos se han enfrentado a muchos conflictos y retrasos inesperados. En este momento, se anticipa que todo el Proyecto estará sustancialmente completo (se reanudarán los patrones normales de tráfico) aproximadamente a mediados de 2024.
