I-5 WIDENING
Transmitted is a sketch of the I-5 widening project limits
within the City of Tustin upon which Caltrans has indicated
milestone dates for key activities. Of particular note is
January 14, 1991 for the closure of all on and off ramps at Red
Hill Avenue. By closing all ramps at one time, it is estimated
that project construction time will be reduced six months from
the �ime anticipated should partial freeway access have been
maintained.
I-5/SR-55 INTERCHANGE RECONSTRUCTION PHASE 2
The construction of the Irvine Boulevard/Fourth Street bridge
structure across SR -55 began in August, 1990. The basic stem
structure will be completed in January 1991, at which time
utilities will be given an opportunity to begin work. Utility
relocation in the bridge is scheduled to be completed in
February, 1991. Bridge construction will then resume and is
scheduled to be completed in April or May, 1991.
Final pavement, signing and striping is scheduled to coincide
with the completion of the Fourth Street bridge crossing I-5 in
Santa Ana. Both structures are scheduled to be opened in
August, 1991.
Demolition of the First Street bridge across SR -55 will begin in
August, 1991, and construction of the replacement structure will
start in October, 1991. Utility relocation into the new First
Street bridge will be in February and March, 1992. The bridge
structure will be completed in May, 1992 with tie-ins signing
and striping completed in June, 1992, when the bridge will be
opened.
The First Street bridge across I-5 in Santa Ana will not be
opened until November, 1992.
A critical path schedule of the project is kept in the
Engineering Division.
