A preliminary report to the Virginia Department of Highways on hard clam (Mercenaria mercenaria) populations in the vicinity of the Hampton Roads bridge-tunnel (I-64) (Segment 268-135D)

1-664 will be constructed in Hampton Roads in an area where the hard clam Mercenaria mercenaria is fished commercially. Because of this c.lam\u27s economic value and because Hampton Roads is the major producing region for this species, it is worthwhile that every precaution be taken during construction of I-664 to minimize the possibility of .damage to this resource. ·To achieve this objective, we are evaluating the possible impact of construction activities around I-64 and adjacent areas on populations of the hard clam. The aim is that if damage or potential damage. is noted around I-64, then construction techniques may be modified during .I-664 construction so that the damage is minimized
