7. Options recommended for further consideration
Left Turn Bay on northbound MD 30 at Mt. Gilead Road
Intersection Control Beacon (ICB)
Hazard Identification Beacon (HIB)

8. Left Turn Bay Concept

9. Left Turn Bay Concept Pros Cons
Provides a separate left turn lane along NB MD 30 thus removing left turners from the through traffic
Large cost for small number of left turners
Significantly reduces the risk for rear-end crashes
Does not correct intersection sight distance deficiency
Maintains minimal shoulders for increased safety and bicycle compatibility
NB and SB shoulders are narrower than existing
Improved grade of Mt. Gilead approach to MD 30 enhancing visibility
Requires utility pole relocation and purchasing right-of-way on the SB side
2 years plus to design and construct after funding is approved
Estimated construction cost = $940,000

10. ICB (Intersection Control Beacon)
MD 30 (Hanover Pike) at Bortner Road/Dover Road

11. ICB (Intersection Control Beacon)
Install Intersection Control Beacon (ICB) at intersection. Beacon would flash yellow along MD 30 and red along Mt. Gilead Road. (12 months plus)
Estimated Construction Cost = $125,000 (Will need approval to qualify for Traffic Management funding.)
ICB (Intersection Control Beacon)
Pros
Cons
Provides additional warning to motorists
Does not correct intersection sight distance deficiency
Identifies the location of the intersection beyond the crest

Moderate cost compared to widening for turn bay
There is concern that a flashing light will affect the the rural character of the roadway and adjacent residence
12 months plus to design and construct after funding is approved
Estimated construction cost = $125,000
