First, the Barstow City Council voted March 1 to approve an $11.6-million agreement with BNSF and the San Bernardino County Transportation Authority that outlines each agency’s role before and during construction. Then, two days later, the SBCTA — lead agency on the project — awarded Anser Advisory Management a $5.9-million contract for construction management services.
