State Route 210 looking south from the Base Line Bridge

The widening of State Route 210 through Highland and the expansion of the Base Line Bridge are both moving forward.

On Tuesday, June 26, the Highland City Council approved a cooperative agreement on $31.6 million for construction and landscaping of the Base Line Interchange with the San Bernardino County Transportation Authority.

Public Works Director Ernie Wong told the council the city will fund 41.9 percent of the interchange project, $13.3 million. Most of the city’s contribution will come from its share of Measure I, the half-cent sales tax increase approved by voters to pay for road improvements.

The transportation authority is scheduled to consider the agreement and a construction management contract at its board meeting on Wednesday, July 11.

The authority received 80 responses to its request for proposal posted in January. In March, an evaluation committee narrowed the choices to four contractors and, after interviews with the four finalists, recommended Dallas-based Jacobs Project Management Co.

The new lanes will be added on the existing unpaved median.

Other features on SR-210 include:

* Rehabilitation of the pavement from Highland Avenue to Lugonia Avenue.

* An auxiliary lane in each direction between Base Line and the Fifth Street/Greenspot Road interchange so drivers won’t need to enter the main lanes of traffic.

* New sound walls in seven locations.

* An acceleration lane heading south off Fifth Street/Greenspot Road.

* A deceleration lane at the eastbound undercrossing at Sterling Avenue to a new two-lane exit at Highland Avenue.

The 3-year interchange project will include “special bridge aesthetic features,” according to the authority’s staff report.

The westbound exit ramp will be widened to two lanes. The westbound and eastbound entrance ramps will be widened from one to three lanes.  And a two-lane exit will be created at the westbound exit connection to the freeway.

The bridge project is expected to begin in May. The freeway widening is scheduled to start in the fall of next year.

The transportation authority meeting is scheduled to begin at 10:30 a.m., following a closed session, at 1170 W. Third St., San Bernardino.

The widening of State Route 210 was terribly needed. And it’s finally happening. The last time I went through the road it was so bad and jammed with traffic that few times I were late to my appointments. I’m glad they are extending it.
