The alkaline earth metal strontium (38 Sr) has four stable, naturally occurring isotopes: 84 Sr (0.56%), 86 Sr (9.86%), 87 Sr (7.0%) and 88 Sr (82.58%). Its standard atomic weight is 87.62(1). Only 87 Sr is radiogenic ; it is produced by decay from the radioactive alkali metal 87 Rb , which has a half-life of 4.88 × 10 10 years (i.e. more than ...

The cities along the proposed route also pushed to prohibit trucks over 4.5 short tons (4.1 t; 4.0 long tons) from using SR 85 (similar to the I-580 truck ban in Oakland and SR 2 truck ban in Angeles National Forest). [3] Thus, SR 85 became one of the handfuls of California freeways that do not allow such tractor semis.
