DISCUSSION
A brief update of the status and schedule of the I-5/SR-55 Interchange
Project follows. The overall project schedule has slipped about three
months. Start-up of the project was delayed until street widening and
revisions to area signalization, intended to mitigate alternate routes for
the project, were completed. Once begun, the interchange project work has
remained well within projected time allowances.
Irvine Boulevard at SR -55 Bridge Reconstruction
This structure is scheduled to be complete and open to traffic in
mid to late December 1991. The Irvine Boulevard bridge across SR -
55 in Tustin, and the Fourth Street bridge across I-5 in Santa Ana
are being reconstructed at the same time. It is possible that the
Irvine Boulevard Structure will be completed prior to the Fourth
Street Structure. If that is the case, and if traffic detouring is
not a problem, then the Irvine Boulevard crossing may be opened
ahead of the Fourth Street crossing, perhaps early December 1991.
First Street at SR -55 Bridge Reconstruction
After the Irvine Boulevard and Fourth Street structures have been
opened for traffic, it will be necessary to reverse the detour
traffic flow before work can begin on the First Street bridge
reconstruction at SR -55. It is estimated that First Street will be
closed and the removal of that SR -55 crossing will begin by
February 1992. The reconstruction of the First Street bridge will
take 12 to 15 months to complete.
As work on this Stage II portion of the I-5/SR-55 interchange reconstruction
continues, Caltrans field engineering staff are working on the details to
dove -tail that current project into the soon to begin Stage III portion of
the interchange reconstruction. Stage III is scheduled to begin construction
in October 1991. Completion of the I-5/SR-55 interchange is set for mid-
1995.
